Equine Metabolic Syndrome

Sun, 01 Mar 2026 15:30:06 GMT

Equine Metabolic Syndrome (EMS) is a common — and often misunderstood — condition that affects many horses and ponies. While it can sound intimidating, EMS is very manageable when it’s recognized early and approached thoughtfully. Understanding the basics can help you protect your horse’s long-term health and reduce the risk of one of its most serious complications: laminitis.

What Is Equine Metabolic Syndrome?

Equine Metabolic Syndrome is a disorder of how a horse’s body processes energy, particularly insulin , a hormone that helps regulate blood sugar. Horses with EMS don’t respond to insulin normally — a problem known as insulin dysregulation .

When insulin levels stay too high, the horse’s metabolism becomes unbalanced, increasing the risk of laminitis and other health issues. While EMS is commonly associated with overweight horses, it’s important to know that not every horse with EMS looks obese .

Why Does EMS Happen?

There isn’t one single cause, but EMS usually develops from a combination of factors:

Insulin dysregulation , which is central to the condition
Dietary influences , especially feeds or pasture high in sugars and starches
Genetics and breed tendencies , particularly in “easy keeper” horses and ponies
Excess body fat , which actively contributes to hormonal imbalance

Some horses are simply more metabolically efficient than o thers — a trait that once helped them survive, but can now work against them in modern management environments.

Common Signs to Watch For

EMS can be subtle, especially in the early stages. Signs may include:

Difficulty maintaining a healthy weight
Fat deposits in specific areas, such as:
A cresty neck
Along the shoulders
Over the tailhead
Around the sheath or udder
A history of laminitis or unexplained hoof soreness

Because not all horses with EMS appear overweight, history and risk factors matter just as much as appearance .

How Is EMS Diagnosed?

Diagnosing EMS involves putting several pieces together:

A thorough physical exam, including body condition and fat distribution
Hoof evaluation and, in some cases, radiographs to assess for laminar changes
Blood testing to evaluate insulin response, which may include fasting tests or dynamic testing such as an oral sugar test

This combination allows your veterinarian to understand not just how your horse looks, but how their metabolism is functioning.

Managing EMS

Nutrition Matters Most

Diet is the cornerstone of EMS management. The goal is to limit sugars and starches while still meeting your horse’s nutritional needs.

This often includes:

Feeding low-sugar forage
Soaking hay when appropriate to reduce sugar content
Managing or limiting pasture access, especially during spring and fall
Avoiding grain and sweet feeds unless specifically recommended

Every horse is different, which is why individualized nutrition plans are so important.

Thoughtful Exercise

Regular, appropriate exercise improves insulin sensitivity and supports healthy weight. The type and intensity depend on the horse — especially if there’s a history of laminitis — and should always be introduced gradually.

Veterinary Guidance

Some horses benefit from additional medical support, but management is always the foundation. Ongoing monitoring helps ensure that adjustments are made before problems arise.

Can EMS Be Prevented?

While not every case is preventable, risk can be reduced by:

Maintaining a healthy body condition year-round
Monitoring pasture intake during high-sugar seasons
Scheduling regular wellness exams and hoof care
Addressing small changes early, before they become big problems

Equine Metabolic Syndrome is common, manageable, and not a diagnosis to fear. With early recognition, thoughtful nutrition, and a strong partnership between owner and veterinarian, horses with EMS can live comfortable, active lives.

If you have concerns about your horse’s weight, fat distribution, or hoof health — or if you simply want to be proactive — we’re always happy to talk. Caring for your horse’s metabolic health is a team effort, and we’re proud to be part of yours.

Suspensory Ligament Injuries in Sport Horses: Recovery Timelines and Return to Competition

Tue, 30 Dec 2025 14:15:01 GMT

One of the hardest things I do is share the new that a client’s horse has sustained a soft tissue injury and one most common questions I hear from our clients is: "How long will my horse be laid up?" Unfortunately, when it comes to suspensory ligament injuries, the answer is never as simple as we'd like it to be. But understanding the injury, the healing process, and the factors that influence recovery can help you make informed decisions and set realistic expectations.

Understanding Suspensory Ligament Injuries

The suspensory ligament (technically the interosseous muscle) is a critical structure that supports or “suspends” the fetlock and absorbs concussive forces during the weight bearing phase of the stride. Its origin is the top of the cannon bone just below the knee and ends at the fetlock. In sport horses, suspensory injuries typically occur in one of two locations:

1. Branch injuries (near the sesamoid bones)
Common in horses landing from jumps or doing sharp turns. Eventers and jumpers frequently injure suspensory branches due to the asymmetric loading during takeoff and landing. Upper-level dressage horses can see chronic injuries to suspensory branches from repetitive stresses from the movements of piaffe, passage and pirouettes.

2. Origin injuries (proximal suspensory desmitis or “High Suspensory” injury)
There is not one event or activity that causes proximal suspensory injuries, and they are quite common in sport horses. It can be caused by a severe overloading or “bad” step or can be due to repetitive stress from overwork. High suspensory injuries can be challenging to diagnose definitively. Diagnosis involves combining a careful palpation exam with a through lameness exam and a high-quality ultrasound examination.

The severity of injury is typically graded on ultrasound which is the most common imaging modality used to diagnose suspensory ligament injuries:

Grade 1: Less than 25% cross-sectional area affected
Grade 2: 25-50% cross-sectional area affected
Grade 3: 50-75% cross-sectional area affected
Grade 4: Greater than 75% cross-sectional area affected

The Biology of Ligament Healing

Here's what makes suspensory injuries particularly challenging: ligaments heal slowly and imperfectly.

Ligament tissue has relatively poor blood supply compared to muscle. The blood supply is what brings in the horse’s immune cells to help clean up the injured tissue and promote growth of new healthy tissue.

The healing process occurs in three overlapping phases:

Inflammatory Phase (0-2 weeks): Initial injury response, with hemorrhage and inflammatory cell infiltration to the site of injury. Heat, local pain, and/or swelling can be seen.

Proliferative Phase (2 weeks to 2-3 months): Fibroblasts produce new collagen, but it's initially disorganized and weaker than the original tissue. Think cross hatch pattern instead of straight lines of collagen.

Remodeling Phase (3 months to 12+ months): Collagen fibers gradually reorganize to straight lines and strengthen along lines of stress. This is the longest phase and continues well beyond when the horse appears sound.

The critical point: ultrasound improvement lags behind clinical improvement, and tissue strength lags behind ultrasound improvement. A horse that trots sound at 90 days may still have significant tissue remodeling occurring. This is why careful monitoring with frequent ultrasound exams and controlled rehabilitation over many months is essential.

Recovery Timelines: The Variables

No two suspensory injuries are identical. Recovery time depends on:

Injury severity: A Grade 1 branch injury might return to competition in 3-4 months. A Grade 4 body injury could require 12-18 months or longer.

Location: Branch injuries typically heal faster than origin injuries but are more likely to become chronic. Origin injuries are often the most challenging and may require 12-18 months to fully heal.

Age and previous injury history: Younger horses with first-time injuries generally heal better than older horses or those with recurrent injuries. Scar tissue from previous injuries affects biomechanics and predisposes horses to reinjury.

Discipline demands: A horse returning to Novice eventing faces different demands than one returning to Grand Prix dressage. The timeline must account for the specific performance requirements.

Quality of rehabilitation: This is perhaps the most controllable variable. A structured, progressive rehabilitation program significantly improves outcomes.

General Timeline Framework

While every case is individual, here's a general framework for moderate (Grade 2) suspensory body injuries :

Weeks 0-4: Strict stall rest or small paddock turnout, depending on injury severity. Anti-inflammatory medications, such a bute, banamine, or Surpass, as needed. This allows the acute inflammatory phase to resolve. Hand walking can usually begin at 2-4 weeks.

Weeks 4-8: Hand walking continues, typically at 10-15 minutes daily and increasing, typically 5-10 min per week. Controlled and quiet walking on flat regular surface. Ultrasound check usually at 4-6 weeks to gauge healing and guide the rehab plan.

Weeks 8-16: If healing appropriately, begin under-saddle walk work. Add ground poles at the walk for muscle development and proprioception. Recheck ultrasound at 8-12 weeks guides next steps. Adding trot work depending on healing seen on ultrasound.

Weeks 8-24: Trot work begins (timing depends greatly on severity of injury and amount of healing)—short intervals initially, on straight lines and good footing only. Underwater treadmill or controlled small hill work can be beneficial for muscle development but very dependent on level of healing. Raised poles at the walk (6”-12”) for proprioception. Increased frequency of ultrasound exams can be helpful during this phase to guide progress. Consider every 3-6 weeks.

Months 6-9: Return to full trot work and introduce canter work carefully, beginning with short intervals on straight lines or large circles. Continue recheck ultrasounds every 6-8 weeks.

Months 9-12+: Progressive return to discipline-specific work. For jumpers and eventers, introduce small fences. For dressage horses, carefully reintroduce collection and lateral work. Competition return depends on discipline, level, and individual horse response.

Why Rushing Fails

I've seen many horses backslide in their rehab because riders—understandably eager to return to competition—push the timeline too aggressively.

Here's what often happens: The horse trots sound at 60-90 days. The rider thinks, "Great, we're almost there!" They accelerate the program too quickly. By 4-5 months, the horse is back in moderate work. At 6 months, they return to competition. Three weeks later, the horse is lame again, often with a worse injury than the original.

The problem? The ligament wasn't adequately healed. Ultrasound showed improvement, but tissue strength hadn't caught up with the demands placed on it.

The most common mistake: allowing time off as "treatment" without structured rehabilitation. Resting or even a small paddock alone doesn't create the controlled loading necessary for proper tissue remodeling. Ligaments need progressive, specific stress to remodel along appropriate lines of tension. This is why we use a very regimented rehab schedule.

The Role of Advanced Therapies

Many clients ask about regenerative or other supportive therapies: stem cells, PRP (platelet-rich plasma), laser, shockwave, and others.

The evidence is growing and we are learning more each month. A great deal of anecdotal evidence and several high quality studies show benefits of the regenerative therapies. In my experience:

Platelet Rich Plasma (PRP), Bone Marrow Aspirate Concentrate (BMAC), or Stem Cells can improve healing quality in many suspensory injuries, but they don't eliminate the need for controlled rehabilitation or dramatically shorten timelines. These therapies can promote a better healing ligament, but they cannot make the ligament heal faster in my experience.
Shockwave therapy can be useful in promoting new blood supply and tissue remodeling, but timing and frequency matter.
Therapeutic ultrasound, Cold Laser (Class III and below) and PEMF (pulsed electromagnetic field therapy) may support blood flow, though evidence is primarily anecdotal.
Class IV laser therapy (photobiomodulation) has solid evidence supporting its use in suspensory rehabilitation. Higher-power lasers penetrate deep enough to reach the suspensory ligament and promote tissue healing through increased cellular metabolism. Class IV laser treatment accelerates the inflammatory phase, promotes collagen synthesis, and improves local blood flow—all beneficial for ligament healing. The typical protocol involves laser treatments 2-3 times weekly during the first 8-12 weeks post-injury. It's not a shortcut to faster rehabs, but it does optimize the healing environment and often improves tissue quality at recheck ultrasounds, but involves significant time and cost.

None of these therapies are magic bullets. They're tools that, when combined with appropriate time, care, and rehabilitation , may improve outcomes. The rehabilitation program remains the foundation of successful recovery.

Maximizing Success: An Integrated Approach

At North Bridge Equine Associates, we take a comprehensive approach to suspensory injuries:

1. Accurate diagnosis: This means a detailed palpation examination, a through lameness examination and a high-quality ultrasound examination by our experienced practitioners. In some cases, we may suggest an MRI study for a more complete picture of the injury. This advanced diagnostic modality helps us to craft a more precise rehab plan and better prognosticate a horse’s return to sport.

2. Individualized rehabilitation protocols: We create specific plans based on injury characteristics, horse signalment, and performance goals. These aren't generic "stall rest for 90 days" prescriptions. We take all the factors into consideration

3. Regular monitoring: Serial ultrasound examinations every 3-6 weeks during rehabilitation allow us to adjust protocols based on healing progress, not just clinical soundness.

4. Integrative veterinary medicine: With two veterinarians certified in acupuncture and two certified in chiropractic treatment, we can address the whole-body compensatory issues that inevitably develop during injury, rest, and rehabilitation. Horses don't just stand still during stall rest—they develop asymmetries, muscular imbalances, soreness in other parts of their body. These compensatory patterns that must be addressed for successful return to work. Acupuncture and chiropractic therapies promote comfort and proper function throughout the rehabilitation process and prepare the horse's entire musculoskeletal system for return to performance.

5. Return-to-work planning: We work with riders and trainers to ensure the return to ridden work is progressive and appropriate for the horse’s discipline. A dressage horse doesn't need to jump but does need careful reintroduction of lateral work and collection.

When to Call Your Veterinarian

Suspensory injuries don't always announce themselves dramatically. Call your vet if your horse shows:

Subtle lameness that's worse after work, resolves after a few days of rest, but then returns
Swelling or heat along the suspensory ligament either behind the knee or on the sides of the fetlock.
Slight shortness of stride, reluctance to push from behind, not wanting to take the long spot, or struggling to hold collection.
Any lameness after a hard workout, awkward movement, or overreach injury

Early diagnosis and treatment significantly improve outcomes. Horses that continue working on mild injuries often progress to more significant injuries that require much longer layoffs.

The Bottom Line

Suspensory ligament injuries test patience. There are no shortcuts, and rushing the process typically means starting over—often with a worse injury. Taking your time pays off!

With accurate diagnosis, appropriate treatment, structured rehabilitation, and realistic expectations, many horses can return to their previous level of work. Success requires partnership between veterinarian, owner, and trainer, with everyone committed to the long-term goal rather than the short-term timeline.

If you suspect your horse has a suspensory injury, or if you're navigating the rehabilitation process and have questions, we're here to help. Our focus on sports medicine means we understand both the medical and performance aspects of getting your partner back to competition soundly.

Targeted Treatments for Back Pain in the Performance Horse

Tue, 23 Dec 2025 16:25:08 GMT

A practical, evidence-based guide for riders and trainers.

Back pain is a common and often performance-limiting issue in sport horses. Once the primary source of pain is accurately identified , choosing the correct treatment—and pairing it with an appropriate rehabilitation program—is essential for durable, long-term improvement.

Below is an overview of the most commonly used targeted therapies for equine back pain, with an emphasis on when and why each treatment is used.

Dorsal Spine (Kissing Spine) Injections

Kissing spine, or impinging dorsal spinous processes, is a frequent cause of back pain—particularly in jumping horses.

Contributing Factors

Genetic predisposition
Poor saddle fit
Inadequate topline and core musculature

Common Clinical Signs

Resistance to working in a frame
Hollow or stiff way of going
Flat or inconsistent jumping style

Diagnosis and Treatment

Diagnosed through:
Careful palpation
Radiographs (X-rays)
Treatment typically begins with targeted injections between affected spinous processes
Reducing pain allows the horse to:
Lift the back
Rebuild muscle
Move more correctly during rehabilitation

Lumbar Facet Joint Injections

Facet joints are small stabilizing joints along the spine that allow controlled bending and flexibility.

When Facet Pain Is Suspected

Stiffness through the back
Uneven bend or asymmetry
Resistance to lateral work
Frequently noted in dressage horses

Treatment

Due to their small size and deep location, injections are performed under ultrasound guidance
Effective therapies may include:
Corticosteroids
Biologic injectables

Mesotherapy

Mesotherapy involves injecting very small amounts of medication just beneath the skin along the back to short-circuit tiny sensory nerves that transmit pain signals to the brain.

Best Uses

Mild to moderate back pain
Muscle tightness
Saddle-related soreness

Key Benefits

Interrupts the pain–spasm cycle
Can be safely repeated as needed

Chiropractic (Veterinary Spinal Manipulation)

Veterinary chiropractic care focuses on restoring normal motion and joint mechanics throughout the spine.

Benefits

Improves spinal mobility
Enhances nerve function and circulation
Supports comfort and performance

Clinical Use

Often incorporated:
As part of routine performance maintenance
During rehabilitation following injury
Must be performed by certified veterinary practitioners

Acupuncture

Acupuncture is a valuable tool for managing muscle soreness, tension, and spasm associated with back pain.

Clinical Advantages

Promotes relaxation and improved muscle function
Can be combined with other therapies

Advanced Techniques

Electro-acupuncture may be used to enhance pain relief and muscle relaxation
Many performance horses benefit from monthly maintenance sessions

Shockwave Therapy

Shockwave therapy is a non-invasive modality used to reduce pain and muscle tension.

Ideal Applications

Secondary back pain due to compensation from other joint issues
Soreness associated with increased workload

Practical Advantages

Helps relax tight muscles and disrupt painful spasm cycles
Many horses tolerate treatment without sedation

Functional Electrical Stimulation (FES)

FES is a rehabilitation-focused therapy that improves muscle activation and symmetry.

Therapeutic Effects

Increases strength and range of motion
Reduces muscle spasm and hypertonicity
Encourages correct use of the back

Clinical Role

Most effective when used alongside other treatments
Particularly valuable during structured rehab programs
Highly effective at building muscle without the horse needing to exercise through targeted treatment

Methocarbamol (Robaxin®)

Methocarbamol is a short-term muscle relaxant commonly used in performance horses.

Appropriate Use

Periods of increased training intensity
To promote comfort throughout competition
Temporary muscle soreness

Important Considerations

Should be used judiciously
Always account for competition withdrawal times

Sacroiliac (SI) Joint Injections

The sacroiliac joint is a ligamentous connection between the spine and pelvis and is critical for hind-end engagement and power.

Common Signs of SI Pain

Difficulty maintaining collection
Trouble with lead changes behind
Resistance in jumping combinations
Bucking or reluctance at the canter

Key Clinical Notes

SI pain is often secondary to issues such as hock arthritis or suspensory ligament disease
It can also occur as a primary source of pain

Treatment

Injections are performed under ultrasound guidance for accuracy
Medications may include:
Corticosteroids (to reduce inflammation)
Biologic therapies (to support tissue health and healing)

A Healthy Back Is the Foundation of Performance

Back pain does not have to end a horse’s training or competitive career.

With:

Thorough diagnostics
Targeted, evidence-based treatments
A tailored rehabilitation plan

Most horses can return to comfortable, confident, and correct performance.

If you suspect your horse’s back may be limiting their potential, early evaluation and intervention make all the difference—because every great performance starts with a healthy, happy back.

Inflammatory Bowel Disease (IBD) and Free Fecal Water Syndrome in Horses

Tue, 04 Nov 2025 15:37:08 GMT

Digestive health plays a critical role in overall equine well-being. Two conditions that often confuse horse owners—and are frequently under-diagnosed—are Inflammatory Bowel Disease (IBD) and Free Fecal Water (FFW) Syndrome . While they differ in severity and impact, both involve disruptions to the gastrointestinal (GI) tract and require thoughtful management.

This article provides a clear, practical overview of equine IBD and FFW , including causes, clinical signs, diagnostic approaches, and current management strategies.

Inflammatory Bowel Disease (IBD) in Horses: What You Need to Know

What Is Equine IBD?

Inflammatory Bowel Disease (IBD) in horses is a condition characterized by an abnormal immune response to substances that are normally tolerated by the gut. These may include:

Dietary components
Normal gut bacteria
Parasites
Environmental antigens

This immune dysfunction damages the intestinal lining by disrupting tight junctions between intestinal cells and weakening the protective mucus barrier. As a result, bacteria and gastrointestinal contents can cross the intestinal wall—a phenomenon commonly referred to as “leaky gut.”

Once the barrier is compromised, immune cells infiltrate the intestinal tissue, leading to chronic inflammation. While the precise trigger for this immune response is still unknown, the downstream effects on digestion and nutrient absorption can be significant.

Common Clinical Signs of IBD in Horses

Horses with IBD may show a wide range of signs, which can vary in severity and consistency:

Mild or recurrent colic
Intermittent or inconsistent diarrhea
Progressive weight loss
Poor body condition despite adequate feed
Severe or acute colic episodes

These symptoms are often caused by:

Altered gut motility
Malabsorption and maldigestion
Poor nutrient utilization
Sugar overflow into the colon
Intestinal thickening or strictures that predispose to colic

Because signs can be subtle or overlap with other conditions, IBD is frequently under-diagnosed.

Diagnosing IBD in Horses

A definitive diagnosis of equine IBD typically requires a combination of exclusion testing and tissue sampling , including:

Biopsy Options

Rectal biopsy
Duodenal biopsy
Full-thickness intestinal biopsy (when indicated)

Additional Diagnostic Tools

Abdominal and thoracic ultrasound
Comprehensive bloodwork
Gastroscopy
Abdominal fluid analysis
Absorption or malabsorption tests

Early diagnosis is critical, as timely intervention can improve both clinical outcomes and long-term survival.

Treatment and Management of Equine IBD

While there is no cure for IBD, many horses respond well to long-term management strategies aimed at reducing inflammation and supporting gut function.

Medical Management

Steroid therapy is commonly used
Typically administered at relatively low doses
Often requires prolonged or lifelong treatment with very gradual tapers

Dietary Management

Small, frequent meals
High-fiber, forage-based diets
Complete feeds when needed
Hay, alfalfa pellets, or hay cubes to improve digestibility

Individual dietary responses vary, making ongoing monitoring and adjustments essential.

Free Fecal Water (FFW) Syndrome in Horses

What Is Free Fecal Water Syndrome?

Free Fecal Water (FFW) Syndrome is a condition in which a horse passes normal, formed manure alongside free-flowing liquid from the anus. While often considered a cosmetic issue, FFW can cause:

Chronic skin irritation
Scalding of the hind legs and tail
Discomfort and secondary skin infections

Causes and Current Research

Despite extensive investigation, no single cause of FFW has been identified . Research suggests that multiple factors may contribute, including:

Gastrointestinal dysregulation
Dietary composition
Stress and social dynamics
Altered hindgut fermentation

Because the underlying mechanism remains unclear, treatment must be highly individualized.

Managing Free Fecal Water in Horses

There is no universal treatment protocol for FFW. Successful management focuses on identifying and addressing potential GI disruptions and environmental stressors.

Management Strategies That May Help

Turnout and Stress Reduction

Adjusting turnout groups
Reducing herd size or social stress

Dietary Modifications

Gradual diet changes only
Free-choice hay for some horses
Chopped hay, hay pellets, chaff, or reduced long-stem forage for others
Psyllium husk supplementation
Table salt (approximately 0.5–2 tablespoons per day, as appropriate)

Supplements and Supportive Care

Omega-3 fatty acids to support normal inflammatory responses
Baker’s yeast to help stabilize hindgut fermentation
Carefully trialing medications or supplements under veterinary guidance

Responses vary widely, so systematic trials and close observation are key.

Skin Care and Hygiene for Horses with FFW

Because FFW often results in chronically wet skin on the hindquarters, proactive skin care is essential:

Keep hind legs and tail clean and dry
Clip excess hair if needed
Apply petroleum jelly or barrier creams to protect the skin
Monitor closely for lesions, scalding, or infection

Final Thoughts: Supporting Equine Gut Health

Both Inflammatory Bowel Disease and Free Fecal Water Syndrome highlight how complex and sensitive the equine digestive system can be. While IBD is a serious medical condition requiring veterinary diagnosis and long-term management, FFW is more common and typically less severe—but still deserving of attention.

Early recognition, individualized care, thoughtful dietary management, and ongoing monitoring can significantly improve comfort, performance, and quality of life for affected horses.

If you suspect GI dysfunction in your horse, consult your veterinarian early—digestive health issues are far easier to manage when addressed proactively rather than reactively.

Equine Eye 101

Tue, 21 Oct 2025 13:37:49 GMT

Bright Eyes, Healthy Horse: Understanding Equine Eye Care

When it comes to your horse’s health, few things are as important—or as delicate—as their eyes. Because horses rely so heavily on vision for safety, communication, and performance, even a small problem can have big consequences. Here’s what every horse owner should know about keeping eyes bright, healthy, and comfortable.

Horses have some of the largest eyes of any land mammal, giving them excellent vision for detecting movement and predators. Positioned on the sides of the head, their eyes provide a wide field of view—nearly 350 degrees—though this comes with some trade-offs in depth perception.

Key features include:

Wide visual field : Horses can see almost all around them without moving their heads, with only small blind spots directly in front of the nose and behind the tail.
Motion detection : Their retinas are highly sensitive to movement, an evolutionary advantage that keeps them alert.
Night vision : A reflective layer (the tapetum lucidum ) enhances low-light vision, helping horses see in dim conditions.

Color vision: Horses are not completely colorblind, but they see a more limited range of colors compared to humans (mainly shades of blue and yellow).

Common Eye Issues in Horses

Because equine eyes are large, prominent, and delicate, they are at risk of injury and disease. Prompt veterinary attention is always crucial, as conditions can worsen quickly and affect vision permanently.

1. Corneal Ulcers

These are abrasions or wounds on the clear surface of the eye. They often occur from trauma (such as a scratch from hay or a branch). Signs include squinting, tearing, and cloudiness. Ulcers can worsen rapidly, so immediate treatment is important.

2. Conjunctivitis

Inflammation of the tissues around the eye may be caused by dust, flies, or allergies. The eye often appears red and irritated. While sometimes mild, conjunctivitis can signal underlying problems.

3. Uveitis (“Moon Blindness”)

Recurrent uveitis is one of the most serious equine eye diseases, causing painful inflammation inside the eye. It is the leading cause of blindness in horses worldwide. Horses may show signs of tearing, cloudiness, or sensitivity to light. Early diagnosis and long-term management are essential.

4. Cataracts

Though less common in horses than people, cataracts (clouding of the lens) can impair vision. They may be congenital (present at birth) or develop later, sometimes after injury or inflammation.

5. Trauma and Foreign Bodies

Because horses often graze in dusty, grassy environments, foreign bodies (like seeds or splinters) may lodge in the eye. Even small injuries can have serious consequences if untreated.

When to Call Your Vet

Any of the following should prompt an immediate call to your veterinarian:

Squinting or holding an eye shut
Excessive tearing or discharge
Swelling around the eye
Cloudiness, blood, or color changes
Sensitivity to light

The golden rule: “If in doubt, check it out.” Eye problems can escalate quickly in horses, so early intervention protects comfort and sight.

Protecting Your Horse’s Eyes

Provide fly masks in summer to reduce irritation and injury.
Keep stables and pastures clear of sharp objects and low-hanging branches.
Minimize dust exposure with good ventilation and clean bedding.
Perform daily checks when grooming—your close attention is one of the best defenses.

The equine eye is as beautiful as it is delicate. By understanding how it works and being alert to early signs of trouble, horse owners play a key role in protecting their horse’s comfort and vision. Our team is always here to help—because a healthy set of eyes keeps your horse happy, safe, and thriving.

Decade One: Keeping Passionate Equine Vets in Practice for the Long Haul

Fri, 03 Oct 2025 20:35:26 GMT

Caring for horses takes a team—and at the center of that team are equine veterinarians. But the reality is that many vets leave equine practice within their first 5–10 years. Long hours, emergency calls, and the stress of running a business can make it difficult for even the most passionate doctors to stay in the field.

For horse owners, that means fewer veterinarians to call on, longer waits for appointments, and the risk of losing trusted relationships just when horses need care the most.

Decade One was created to change that.

What is Decade One, you ask?

Founded in 2015 by Dr. Amy Grice after decades as an ambulatory equine practitioner, Decade One was designed to give young veterinarians the tools, community, and encouragement they need to build long and successful careers in equine medicine.

Instead of focusing on clinical skills (which veterinary school already covers), Decade One helps early-career vets with the real-world challenges of practice: business decisions, financial planning, leadership, communication, setting healthy boundaries, and finding balance in a demanding career.

How It Works

Decade One brings veterinarians together in small groups, called cohorts, that meet regularly over the course of three years. These gatherings—both in person and online—give doctors a chance to:

Learn about the business side of veterinary medicine
Share experiences and advice with peers who face the same challenges
Build relationships that last long after the program ends

This supportive network means that when your vet faces tough situations—whether it’s pricing services, handling emergencies, or balancing the demands of practice—they have resources, mentors, and colleagues to lean on.

Why This Matters for You and Your Horses

For horse owners, Decade One’s impact is far-reaching:

More vets in practice means better access to care when you need it.

RRP Journey Update: Making Great Progress!

Tue, 02 Sep 2025 04:00:23 GMT

Weekend Wins and Big Plans Ahead

We’re celebrating a fantastic milestone for both Gus and Jasmine, who tackled their first Beginner Novice (BN) at Valinor with style and determination! Gus brought home a 5th place finish, while Jasmine followed closely behind in 6th—an impressive debut for this dynamic duo.

Not one to rest on his laurels, Gus headed to Coursebrook this past weekend for another BN outing. He delivered a confident, penalty-free performance, finishing on his dressage score of 36. No jump faults, no drama—just a smooth, focused ride that showed how much he’s growing with every outing.

Next up: Gus is gearing up for his first recognized BN at GMHA in September. We’re excited to see how he rises to the occasion on a bigger stage.

Jasmine is making progress with her jumping skills as reported by Adrienne. She has the athleticism and scope and is becoming more educated by the day. She has her feelings about some of the questions, as mares do, but she is proving her drive to find the correct answer is there!

Stay tuned—this is just the beginning!

RRP Journey Update: IM Adequan® in the Young Horse

Thu, 28 Aug 2025 16:46:54 GMT

Update from one of our RRP Sponsored riders, Julia Grella, about the benefits seen of Adequan IM injections in her 4 year old OTTB

"In preparing a horse to compete at the Thoroughbred Makeover in Kentucky, you have a limited window of time in order to train your Thoroughbred to a certain level. This year I am taking a lovely 4 year old Thoroughbred, Magnetic Appeal (also known as Gus) with hope to compete in both the Dressage and Eventing disciplines. Due to the pressure that inevitably accompanies this preparation, I try to think of options to alleviate any associated stress or discomfort.

I spoke to Dr. Fred Nostrant, Gus’s veterinarian, about ideal, non-invasive options for joint support while we introduce Gus to proper flat work and low level jumping. His primary recommendation was Adequan® injections. Adequan® i.m. polysulfated glycosaminoglycan (PSGAG) solution is a safe, effective option for horses that need support for non-infectious degenerative and/or traumatic joint dysfunction of the carpal and hock joints.

The standard loading dose is a series of 7, 5ml intra-muscular injections given every 3-4 days. I loved this idea for Gus because given he is only 4 years old, I did not think he was ready for joint injections, but wanted to get ahead of any discomfort he may be experiencing as he grows and learns.

I have already been impressed with the changes and development I am seeing since starting Adequan®. He has demonstrated increased levels of comfort in his willingness to work, and I have noticed he easily canters on the correct lead, while also being quicker in the transition. I have noticed that he is pushing off more evenly over fences, and exhibiting more thoroughness in his flat work. I have even started to ask for more advanced lateral work movements and he has been happy and willing.

I have also noticed physical changes in Gus since he has been more comfortable. His improved way of moving has contributed to better muscle development over his entire topline and hind end. We still have a long way to go before the Makeover, but I am so excited about the changes I am seeing.

Overall, if you are looking for an easy, non-invasive way to help your horse, definitely consider asking about Adequan® as an option. I am so grateful to the North Bridge Equine team, and Dr. Nostrant for their continued guidance on this journey."

Contact your vet to ask if Adequan® IM injections would be right for your horse!

Cuts, Scrapes, and Kick Wounds - Oh my!

Wed, 20 Aug 2025 15:47:51 GMT

What to look for, how to treat simple wounds, and when you should call the vet

First Aid for Minor Horse Injuries: What to Do Before the Vet Arrives

As horse owners, we all know that heart-dropping feeling when we find a horse limping or notice an unexpected cut. Feeling nervous is normal. The good news is that many minor injuries can be managed safely at home with calm, careful steps.

This guide will help you:

Stay focused during the initial assessment
Provide basic first aid for simple wounds
Recognize emergencies
Gather the information your veterinarian will appreciate if you need to call

Step One: Observe Before You Act

Don’t panic. Take a breath.
Before touching anything, take a moment to watch your horse and assess the situation.

Body Language

Ask yourself:

Is the horse standing quietly or restless?
Is weight being shifted repeatedly from leg to leg?
Is the horse willing to bear weight on the injured limb?

Calm behavior often indicates a less severe injury, while agitation or refusal to stand may signal pain or shock.

Vital Signs to Check

Heart Rate

Normal adult horse heart rate: 36–48 beats per minute (bpm)

Respiration

Observe breathing:
Is it rapid?
Labored?
Are the nostrils flared?

Temperature

Normal range: 98.0–100.7°F
Temperature may be slightly higher if:
The horse is stressed
The horse has been standing in the sun

Abnormal vital signs can indicate pain, infection, or shock.

Bleeding and Signs of Shock

Evaluate Bleeding

Is there active, heavy, or pulsating bleeding ?
Is blood pooling or soaking through bandages quickly?

Watch for Signs of Shock

Very fast heart rate
Rapid breathing
Cold ears or limbs
Bright red or pale gums
Sweating without exertion

�� Emergency Alert
If you see heavy bleeding, rapid breathing, sweating, or signs of shock, call your veterinarian immediately . These situations require professional care right away.

Quick Definition: What Is Shock?

Shock occurs when the horse’s organs are not receiving enough blood due to:

Blood loss
Severe infection

Common Signs of Shock

Very fast pulse ( over 100 bpm )
Cool ears or legs
White or bright red gums
Dilated pupils
Rapid breathing

Shock is life-threatening and requires immediate veterinary attention.

Step-by-Step Guide for Simple Wound Care

If your horse is:

Calm
Bearing weight
Bleeding lightly

You can begin basic first aid.

1. Clean the Area

“Dilution is the solution to pollution.”

Rinse the wound thoroughly with clean water
Hose water is perfectly acceptable

2. Stop the Bleeding

Apply a clean cloth or gauze pads
Maxi pads work exceptionally well
Secure with a light Vetrap bandage

If bleeding continues:

Do not remove the soaked layer
Add fresh padding on top and continue pressure

⚠️ Severe Bleeding Note
In cases of serious bleeding:

Apply firm pressure
Add more padding and tighter wrapping as needed
You should already be on the phone with your veterinarian

3. Disinfect the Wound

Gently clean with Betadine scrub , if tolerated
Avoid:
Hydrogen peroxide
Rubbing alcohol

These products damage healthy tissue and slow healing (and alcohol burns).

4. Apply Medication

Acceptable topical options include:

Neosporin
Silver sulfadiazine (SSD)
Furacin

5. Apply a Bandage

Use soft padding (cotton roll or clean gauze)
Apply Vetrap lightly over padding (not tight for minor wounds)
Tuck in the ends to prevent unraveling
Place a No-Bow and standing wrap over the bandage

Bandage Care

Check bandages twice daily
Remove every 12–24 hours
Re-clean the wound
Re-apply medication
Use fresh padding and a clean wrap

Watch for Infection: Warning Signs

Some wounds can worsen instead of heal. Monitor closely for:

Increasing swelling
Heat around the wound
Thick or foul-smelling discharge
Worsening lameness
Fever
Excessive pain or sensitivity

When to Involve Your Veterinarian

Certain injuries always require professional care .

Deep Puncture Wounds

Examples:

Stepping on a nail
Impalement by fencing or sharp objects

Why these are dangerous:

Bacteria can be trapped deep inside

Important:
If it can be safely avoided, do not remove the object . Leaving it in place helps the veterinarian assess the wound path using X-rays or ultrasound.

Joint or Tendon Injuries

Wounds or swelling near:

Hocks
Knees
Fetlocks

Tendon Injury Clues

Extensor tendon damage:
Horse knuckles over
Difficulty placing the hoof flat
Flexor tendon damage:
Fetlock drops
Toe lifts off the ground
Suspensory ligament injury:
Generalized swelling or swelling along the sides of the fetlock
Noticeable fetlock drop
Lameness

Severe Lameness

Horse will not put weight on the leg

This may indicate:

Fracture
Severe soft-tissue injury

Final Guidance

In serious cases:

Call your veterinarian first
Follow their instructions until they arrive

Early veterinary care can prevent long-term complications and improve outcomes for your horse.

Staying calm, observant, and prepared makes all the difference.

In these cases, call your vet first and follow their instructions until they arrive.

Early veterinary care can prevent long‐term problems.

RRP Thoroughbred Makeover Sponsorship

Wed, 18 Jun 2025 14:59:35 GMT

Supporting our clients in their journey with their OTTBs

In the heart of Apple Knoll Farm, two dedicated horsewomen and long-time clients of NBEA, Adrienne Iorio and Julia Grella, are embarking on an extraordinary journey—one filled with transformation, determination, and the undeniable spirit of the Thoroughbred.

Their partners in this challenge, Jasmine (Caribbean Night) and Gus (Magnetic Appeal), are no strangers to the competitive world. Once fierce contenders on the racetrack, these athletic Thoroughbreds are now stepping into a new chapter, where training meets trust, and a second career takes shape. Through the 2025 Retired Racehorse Project Thoroughbred Makeover, they will evolve into polished competitors, their talents shining brightly on the grand stage of Kentucky Horse Park this October.

But this isn’t just about competition—it’s a celebration of possibility. The Thoroughbred Makeover, hosted by the Retired Racehorse Project (RRP), is the largest Thoroughbred retraining event in the world, proving time and time again that these horses are more than their race records. With disciplines ranging from dressage and show jumping to ranch work and eventing, the Makeover showcases their adaptability, heart, and limitless potential for success beyond the track.

Meet the Stars of the Journey:
Caribbean Night ("Jasmine") – A 2019 mare by Cross Traffic, Jasmine left her mark on the racing world with 28 starts, 3 wins, 7 seconds, and 4 thirds, earning $67,416 along the way.

Magnetic Appeal ("Gus") – A 2021 gelding by Enticed, Gus showed promise with 12 starts, 2 wins, 1 second, and 1 third, securing $24,400 in earnings before finding his way to this exciting new challenge.

As we cheer on Adrienne, Julia, Jasmine, and Gus, we celebrate not just their hard work, but the incredible journey of all off-track Thoroughbreds that make up a large percentage of the horses that we work with and support—their resilience, their versatility, and their boundless future beyond the track.

Functional Electric Stimulation: A Research-Backed Approach to Equine Recovery

Fri, 30 May 2025 14:29:07 GMT

How FES Supports Muscle Function, Circulation, and Healing

Functional Electrical Stimulation (FES) has recently become an increasingly well utilized modality in equine sports medicine and rehabilitation.

FES is designed to restore the natural cycle of muscle contraction and relaxation, encouraging movement patterns that contribute to recovery and long-term function. Originally developed for human patients recovering from spinal cord injuries, there is a wealth of data behind its mechanism and use. Here we explain how it works and how it can help our equine partners.

The Science Behind FES

In healthy muscles, there is a continuous balance of contraction and relaxation, allowing movement to occur fluidly and without restriction. However, when an injury occurs, muscle fibers enter a protective state, often remaining in prolonged contraction. This response, sometimes referred to as muscle "splinting," prevents excessive movement but also reduces circulation and increases inflammation—both factors that slow recovery and result in pain.

FES works by delivering controlled electrical impulses that target both motor and sensory nerves, prompting muscles to contract and relax in a way that mimics their natural function. By encouraging this cycle, FES helps:

Restore proper movement patterns that are disrupted by injury or chronic poor usage
Improve circulation to bring essential nutrients and oxygen to damaged tissues
Reduce chronic inflammation
Prevent long-term stiffness and adhesions, allowing for more functional recovery

FES vs. TENS: Key Differences in Their Effects

While FES and Transcutaneous Electrical Nerve Stimulation (TENS) are sometimes mentioned together, they serve different purposes:

FES stimulates motor nerves, activating muscle movement and function, in addition to working on sensory nerves to reduce pain while TENS primarily affects sensory nerves to modulate pain signals.

FES promotes muscle coordination, encouraging proper movement patterns, while TENS is more focused on pain relief rather than functional recovery.

FES reaches deeper tissues, stimulating muscles up to 6 to 8 inches beneath the skin, whereas TENS has a more surface-level effect on nerve endings.

These distinctions make FES particularly useful in cases where muscular dysfunction, imbalance, or limited mobility are present, rather than simply addressing pain alone.

Applications in Equine Rehabilitation

Because of its ability to penetrate deep muscle layers, FES has proven valuable in treating conditions affecting the spine, pelvis, tendons, and ligaments—areas that can be difficult to address through manual therapies alone. Research and clinical applications suggest that FES may assist with:

Post-injury recovery - particularly after strains or soft tissue damage
Neuromuscular re-education - helping muscles regain coordinated movement
Arthritic conditions - where muscular compensation patterns contribute to joint strain
Preventing muscle wastage and atrophy - (particularly of the back) while horses are recovering from surgery or other injuries.
Preventative care - reducing the risk of secondary injuries caused by imbalances in movement

Another notable advantage of FES is that horses tend to tolerate the treatment comfortably without requiring sedation. The stimulation itself is designed to be gentle yet effective, making it a practical option for both acute and chronic cases.

A Research-Backed Approach to Recovery

While electrotherapy has been used for decades in human medicine, its adaptation to equine care continues to evolve. FES aligns with fundamental rehabilitation principles, emphasizing controlled activation of muscles to support healing and functional movement restoration. As its applications in veterinary medicine expand, researchers continue to explore how FES can further optimize rehabilitation protocols for equine athletes and companions alike. As research progresses, its role in performance recovery, injury prevention, and therapeutic intervention will likely continue to grow.

Spring Wellness Exams and Vaccines

Mon, 24 Mar 2025 00:00:00 GMT

Keeping your horse healthy coming out of winter and into the more active time of year (for all of us)

North Bridge Equine offers a comprehensive preventative care and vaccination program for your horse. Sport horses usually receive vaccinations divided into 2-3 appointments approximately two weeks apart. Pleasure horses may receive vaccination in 1 or 2 visits dependent on use, age, and any history of reactions to vaccines. We suggest spring vaccination be completed between March and May.

Why do we vaccinate?

Communicable diseases are frustrating, costly, time consuming and sometimes scary. Fortunately we have effective vaccines that can reduce the risk of contracting disease or the severity in the event your horse does actually get sick. While no vaccine is 100% effective, the efficacy and safety of the vaccines we administer to horses is very high. North Bridge Equine selects the vaccines we use based on efficacy studies and low reactivity levels. While some horses may still react to vaccines, there are methods we can use to decrease the severity of reaction. Rarely does a horse have a consistently severe enough reaction or other co -morbid condition that may make vaccination inappropriate. For these horses we recommend vaccine titers to target which vaccines they need and when.

Why can’t we just do titers and forego vaccination altogether?

The beauty of vaccination in livestock that live in groups is a phenomenon called herd immunity. This means that if the majority of the population is protected against disease through natural exposure or vaccination, the few that either don’t respond to vaccination, get missed, or can’t be vaccinated for medical reasons are effectively protected as well. Once we stop vaccinating the herd immunity rate goes down and every animal is more at risk. While titers are useful for specific cases, we use them sparingly and in cases of medical need in order to protect the immunity of the herd. If we didn’t vaccinate and simply titered everyone it’s possible that the herd immunity could fall low enough to have breakthrough disease.

What vaccines do we recommend?

Potomac/Rabies combo-
Rabies is an invariably fatal virus. Rabies vaccine is the most effective vaccine we have available and due to the possibility for human exposure, is required by NBEA to be a patient. Potomac horse fever is a mayfly/snail vectored bacterial disease that is more prevalent near water and in wet conditions. While we fortunately did not see much of this disease in the Northeast for many years, it has become more common in recent years.
EWT/WNV-
Eastern and Western Equine Encephalitis (EEE & WEE) & West Nile Virus are neurologic viruses which spread to horses by mosquitos. These are diseases are usually fatal. The diseases cannot be spread from horse to horse. The immunity for EEE and WEE is short lived providing protection fro only about 6 months in most horses. NBEA recommends a once yearly vaccine in the spring for all horses with boosters in the late summer of the local prevalence of disease is high and before traveling south for winter. EEE is usually fatal but some horses can pull through with extreme supportive care.
Tetanus-
Tetanus is caused by the toxin of a soil bacteria that infects horses through puncture wounds or lacerations. It causes complete paralysis, including the heart. Horses are uniquely susceptible to tetanus and require annual booster of this vaccine.
Influenza/Rhinopneumonitis ("Flu/Rhino")-
These are viral infections of the respiratory tract causing fever, cough and nasal discharge. While rarely fatal, they are extremely contagious and spread rapidly through barns and show grounds. This vaccine is required within 6 months for all horse’s showing at USEF rated shows.
Strangles-
A bacteria that is highly infectious to horses of any age. It is transmitted through direct contact of infected horses and indirect contact with anything the infected horse is in contact with, including handlers, buckets, tack, ect. Common clinical signs include fever and thick nasal discharge. Noteworthy is that Strangles is classified as a reportable disease in Massachusetts, triggering mandatory quarantine measures for affected farms. While the vaccine can be administered intranasally or orally, it does not provide full immunity but effectively reduces the severity of the illness.
Botulism-
Another bacterial spore borne disease, botulism is fatal without early diagnosis and treatment. It is present in the dirt in some geographic regions and can be found in contaminated water and round or compressed hay bales. The vaccine is highly effective and has one of the lowest reactivity rates. We recommend this vaccine to anyone feeding round or compressed bales or horses traveling south to Aiken for the winter.

Penny's Healing Journey: Overcoming a Devastating Injury

Mon, 24 Feb 2025 15:38:45 GMT

Follow Penny’s incredible journey from injury to jumping crossrails once again

Penny is a smallish and fairly plain 18-year-old chestnut Quarter Horse mare who came to NBEA with a history. Penny definitively did NOT like the vet. She would break out into a sweat when she heard the truck drive in and had to be cornered and lip-chained in the stall to get sedation for whatever procedure needed to be performed. And Penny, unfortunately, needed the vet a lot. Her registered name is "Mama’s Last Cent," and she has definitely put that name to the test.

Dr. Shen prides herself on her fear-free approach and has a proven track record with needle-shy horses. Penny has now been Dr. Shen’s patient for almost 10 years and has been entirely reformed, no longer afraid of needles. Her owner can walk into her stall and give her Adequan without even a halter on. Penny is one of Dr. Shen’s favorite patients. And Dr. Shen is one of Penny’s favorite people.

Two years ago, on New Year’s Eve, Dr. Shen was on call and received an emergency call from Penny’s owner. Penny was standing in her paddock in the rain and wouldn’t or couldn’t move. Dr. Shen headed out to assess the situation and arrived to find Penny in the barn but very lame on her left front. After an abscess was preliminarily ruled out, X-rays were taken to rule out a fracture. While no major bone fracture was present, Penny did have a few very small bone fragments around her pastern joint associated with the ligaments that hold the pastern joint together as well as a subluxation of the joint. Part of the cartilage was obviously crushed on X-ray, and the bones were no longer in straight alignment. Ultrasound revealed a full tear of the lateral collateral ligament of the pastern. Penny’s leg was treated to decrease pain and swelling, and anti-inflammatory medications were given. The prognosis for a return to riding soundness was poor and while pasture soundness would have been acceptable, it was also not guaranteed.

Dr. Shen decided to place a cast on Penny’s foot from the pastern down, called a slipper cast. While Penny was still lame at the walk, the severity significantly improved as soon as the cast was on.

Over the next 3 months, Dr. Shen and her technician Sheena placed a series of 3 casts on Penny. Even though she was confined to her stall and a stall-sized pen complete with a pop-up tent shade just outside her stall, Penny was an exemplary patient. She also ate a lot of hay and donuts (not prescribed by Dr. Shen).

Over the next year, Penny’s soundness increased, and Dr. Shen was optimistic that pasture soundness was a reality. Penny would frequently let herself out and graze all over the farm, visiting all her friends and taunting them with her freedom. Despite this unauthorized exercise, Penny behaved herself and never ran. She provided her own physical therapy that year and thrived in the no-expectation environment.

One day, her owner watched tearfully as Penny trotted across the paddock and wasn’t lame on her left front (although she may have been lame everywhere else since it had been so long since she had any maintenance). But most importantly, she wasn’t lame on the left front! At this point, Dr. Shen rechecked Penny and cleared her for starting some walking rehab under saddle.

It’s now been more than 2 years, and Penny has surpassed all expectations for her recovery. She enjoys giving some light lessons, although sometimes the chestnut mare comes out and she bucks kids off. She has even recently been jumping some small crossrails, which is her absolute favorite, next to donuts of course.

"Zombie" Eye Enucleation

Wed, 15 Jan 2025 18:22:45 GMT

Managing Chronic Conditions for Optimal Health and Comfort

Many of you have had the privilege of meeting Dr. Cory's technician, Jenna, who is a lifelong horsewoman passionate about ensuring that horses have a good home, even in their older years. Recently, Jenna bought her very own little hobby farm, lovingly named "Barney's Home for Broken Creatures"—a fitting name considering she also has two "broken" cats!

The farm's namesake is Barney, a 23-year-old plain bay gelding of dubious breeding. Barney is a kind and easygoing horse who has taught many kids to ride and has been with Jenna on and off throughout the years. Unfortunately, last year, Barney's teaching career ended due to an intractable knee injury that was only minimally responsive to treatment, making surgery no longer a viable option. However, he remains perfectly comfortable eating lots of food all day and policing the paddock.

Once Barney was home and settled, there was at least one empty stall that clearly needed to be filled. Jenna and Dr. Cory met Flash when asked to examine him for his declining performance in a lesson program. Flash was reported by his current owners to be approximately 18 years old, with an entirely gray right eye, headshaking, and a myriad of musculoskeletal issues. Upon examination by Dr. Cory, it was noted that Flash was more likely around 30 years old and no longer fit for work. Thus began his cushy life at "Barney's Home for Broken Creatures".

Dr. Cory and Jenna developed a successful management program to help Flash gain weight, be more comfortable in his body, and overall much happier. Dr. Shen, who enjoys diagnosing and treating eye problems, was asked to look at Flash's gray eye. Both Jenna and Dr. Cory were suspicious that the gray eye, while appearing fairly normal, was a source of significant pain and possibly contributed to the headshaking. Dr. Shen's exam revealed that Flash was totally blind in that eye and suffering from chronic endothelitis, severe inflammation of the back side of the cornea (the clear windshield-like portion of the eye). Medications were tried to alleviate suspected pain, but no changes were observed. Consequently, the decision was made to remove the eye in hopes of providing more comfort.

On a frigid day a few weeks before Christmas, Dr. Shen and Dr. Cory teamed up to remove Flash's eye at Jenna's farm. Flash was sedated, given pain medication, and the tissue surrounding the eye and the area behind the eyeball were numbed with local anesthetic (similar to Novocaine). Dr. Shen removed the eyeball and closed the overlying tissue, and Flash did exceptionally well, given his age. In the following weeks, Jenna noted that Flash's headshaking improved dramatically, and his neurotic behavior decreased.

While retaining non-painful, ideally visual eyes in horses is a priority, there are times when removing the eye is a better option for both the horse and the owner. Horses with chronically painful eyes that are removed often become noticeably more comfortable than expected, making it clear they were in more pain than they had shown previously. While standing enucleation is generally straightforward (albeit gruesome) and well-tolerated by most horses, there are some instances where general anesthesia at the hospital is a better option.

Flash has been doing very well, and Jenna is very happy. Now, we just need to work on getting his 16 bad teeth dealt with!

Navicular Disease

Wed, 18 Dec 2024 19:54:40 GMT

A small bone that can be a big problem

Navicular disease is a long term, degenerative condition of the navicular bone and sometimes the surrounding soft tissue structures. It involves damage within the navicular bone itself, and breakdown of cartilage on the surface of the bone. It can also involve inflammation and damage to the neighboring navicular bursa and deep digital flexor tendon. It is one of the most common causes of longterm forelimb lameness in athletic horses. Navicular is essentially unknown in ponies and donkeys.
The exact cause is unknown, but it may involve increased pressure on the navicular bone and its blood supply. It most often is a disease of a more mature horse, commonly not appearing until 8 to 10 years of age. Navicular disease may be partially hereditary. Navicular disease is more common in Warmblood horses, Quarter horses, and Thoroughbreds. Inadequate or poor shoeing, poor conformation, and trauma can also be contributing factors.

Typically, navicular disease is slow and subtle in onset. One or both forefeet can be affected or just one. It is very rare to see navicular disease in a hind foot. Lameness tends to come and go in the early stages of the disease. Stride is shortened and the horse may tend to stumble. Turning a horse in a tight circle usually produces a short-term worsening lameness. Muscle soreness in the shoulder develops after compensatory changes in posture or gait, resulting in the common complaint of "shoulder lameness".

Diagnosis is made with a complete history, careful examination, radiographs and potentially peripheral nerve blocks. Radiographs may show degenerative changes involving the navicular bone, including possible abnormal ingrowths of bone and bone reshaping. A palmar digital (heel) nerve block will readily abolish the lameness. In bilateral disease the lameness frequently then becomes apparent on the unblocked limb.

Navicular disease can be managed but not cured. Appropriate hoof trimming, shoeing and corrective shoeing can help restore normal bone alignment and balance. Non-steroidal anti-inflammatories such as Equioxx, and bisphosphonates such as Osphos can extend serviceable soundness in some horses. Injection of corticosteroids into the coffin joint or navicular bursa may relieve pain but is not curative.

Surgical removal of part of the palmar digital nerve ("denerving") may provide relief from pain and prolong usefulness of the horse but is not curative. Surgical removal of nerves can be accompanied with severe complications and may not be recommended for every horse.

Dr. Fred's Travel Log Part 1

Tue, 13 Aug 2024 17:45:29 GMT

Off to Saudi Arabia!

Dr. Fred spent the spring and early summer traveling the world with the US Dressage Team as one of the Team Veterinarians. Here is the first installment of Dr. Fred’s Travel Log!

In April Dr. Fred flew halfway around the world to Riyadh, Saudi Arabia to serve as Team Veterinarian for the US Dressage Team at the prestigious World Cup Finals. 56 horses from around the world joined in Riyadh for the finals of the World Cup in dressage and jumping. Dr. Fred picks it from here:

I left Boston on Tuesday night and arrived in Riyadh, Saudi Arabia on Thursday morning. All the horses arrived at the amazing venue at the same time which made for a bit of chaos for arrival vet exams but all the American horses were very well behaved. The venue was the Riyadh Convention Center, which was expertly converted to a horse show grounds in a matter of days as when we arrived it was still very much under construction. The horses were stabled in one enormous, enclosed tent that was kept comfortable with 6 huge air conditioners running 24/7. Given the average daytime temperatures were well above 95 degrees the horses (and people) sure appreciated this. As the horses settled in, I marveled at how quickly the organizers turned an empty convention hall into the World Cup show arena and enormous warm-up arena separated by a three-floor tall broadcast tower, riders lounge and press area. Surrounding over half the arena were the VIP areas with luxurious seating areas all constructed in a matter of days and the entire VIP section had been sold out for months. With the intricate lighting and thundering music, it made for an impressive atmosphere!

The daily routine in the days before competition was morning exams on Team USA horses followed by training rides for each of the horses. It was an amazing experience to not only observe the top US horses train but also to watch the world’s best horses and riders such as Isabelle Werth and DSP Quantaz, Patrick Kittel and Touchdown, and Charlotte Fry and Everdale. In the heat of the middle of the day was time for the horses to rest and recharge. After evening feeding and checks the team would gather for dinner. We explored many local Riyadh restaurants and I marveled at the amazing local cuisine!

It was not all work all the time, and I had some time to explore Riyadh with the highlights being a bustling street bazaar, the breathtaking Kingdom Tower, and the historic Diriyah museum. The Kingdom Tower is the tallest building in Saudi Arabia with an observation deck at the top. This observation deck is suspended between the two towers and gives incredible views of Riyadh and the surrounding desert. The Diriyah historical site is the birthplace of the Saudi state as the original home of the Al-Saud family. Wandering through the historic stone buildings and alleyways of the Diriyah brought me to the Saudi Museum of the horse which was specular. I was fascinated by the rich history and the deep bond between the Saudi people and the Arabian horse.

Let’s meet Team USA: the World Cup Dressage team is made up of Indeed: a very proud and talented mare who loves her food and her personal space (as many mares do), Duenensee: a very tall and sweet gelding who travels with two large stuffed emotional support animals(check out “Duenensee Dressage” on TikTok for a video of Dueney and his penguin), and Fayvel: a goofy gelding who loves his treats but turns on game face and shows some serious dressage skills. This young team did very well considering the very stiff competition ending the week with Fayvel in 8th place, Indeed in 12th place, and Duenensee in 13th place in the Grand Prix Freestyle. It was incredibly fulfilling to be part of such a cohesive and supportive team while caring for these remarkable horses.

This was the experience of a lifetime to be able to care for these amazing athletes at the top level of the sport in a part of the world so different from home. The people of Saudi Arabia were so kind and gracious, the food was amazing, and the scenery of the country was breathtaking. I am honored to be part of Team USA and to support our horses and represent our country on the international stage!

Stay tuned for the next installment of Dr. Fred’s Travel Log, featuring his adventures in France and Germany as Team USA prepares for the Olympics in Paris!

Allergies in Horses

Thu, 20 Jun 2024 14:28:14 GMT

Causes, ways to manage, and how to keep your horse comfortable

At all times a horse’s body is under siege from the abundance of microorganisms present everywhere. A healthy immune system keeps these minute organisms at bay as inflammatory cells wage invisible battles to repel foreign proteins (antigens) attempting to invade the body. Normally, the immune system holds its line of defense without the horse even knowing that its immune system is at work.

When microbes invade and colonize, a horse shows clinical signs of disease. But occasionally, an immune response overreacts to a noninfectious cause. Such a hypersensitivity response is referred to as an allergy; it can range from a serious, life-threatening systemic reaction (anaphylaxis) to a mild, but disagreeable, skin reaction such as hives or itching.

The immune system of a horse diligently monitors for any potential threats, producing specific antibody proteins targeted at particular antigenic triggers. Surprisingly, an allergic reaction does not typically occur upon initial exposure to an allergenic protein. It is only when the skin becomes sensitized and encounters the allergen again that clinical signs manifest.

The perplexing nature of hypersensitivity reactions in horses is further compounded by their gradual development over weeks, months, or even years. Consequently, the sudden appearance of hives cannot always be attributed to recent changes, making it challenging to pinpoint the exact source of the issue. This intricate interplay between the horse's immune system and allergic responses underscores the importance of careful observation and comprehensive understanding in managing equine health effectively.

Urticaria, commonly known as hives, can be triggered by a multitude of factors. Medications like antibiotics, antiparasitic drugs, and hormones, as well as certain vaccines, have been identified as potential culprits. Additionally, foods such as plants, hay, and supplements can also lead to urticaria. Hypersensitivities, including adverse food reactions, contact allergies, and genetically linked atopy, can play a significant role in the development of this skin condition. In some cases, urticaria may arise from infections caused by bacteria, fungi, or parasites, or even from stings by insects.

The mechanism behind urticaria involves allergen-specific antibodies (immunoglobulin E or IgE), which upon initial exposure, prime mast cells and basophils for a Type I hypersensitivity reaction upon subsequent encounters with the allergen. This process leads to the release of biochemical substances like prostaglandins and histamines, triggering an inflammatory response. Understanding the diverse causes of urticaria is crucial in effectively managing and treating this condition.

When dealing with hives in horses, it is beneficial to act promptly and seek professional advice. If your horse is experiencing an acute allergic response, contacting your veterinarian immediately is essential. While hives may not bother some horses, others may itch and feel discomfort. In such cases, providing cool water soaks can offer relief. However, it is generally advised not to administer any medications before your veterinarian assesses the situation. Hives typically resolve on their own within one to two days and do not significantly impact the horse's overall health.

In more severe instances, treatment with epinephrine and corticosteroids may be necessary. Although antihistamines may not be highly effective for acute hives, medications like hydroxyzine or cetirizine could help in limiting the allergic response. Remember, the well-being of your horse is paramount, and consulting with a veterinarian for proper evaluation and guidance is always recommended in such situations.

In the event of an allergic response in your horse, it is crucial to distinguish it from infections such as skin parasites or bacterial/fungal infections like ringworm. Administering corticosteroids without proper differentiation can exacerbate a mild infection, transforming it into a severe and challenging issue to address. One key indicator is the rapid hair loss within a few days in cases of ringworm, contrasting with the absence of hair loss in hives. Should hives manifest, prompt action involves discontinuing any new medications or food supplements. The principle of 'less is more' is emphasized, advocating for the removal of all supplements and herbs from the horse's diet except for hay, rather than attempting to resolve the issue by introducing additional supplements. This approach can prove to be more effective in managing the condition.

You can also consider alternative methods alongside conventional Western medical treatments. Holistic therapy, such as acupuncture, can be effective in addressing allergic problems directly. Whether the medical approach is rooted in Western or Eastern philosophy, it is crucial to avoid exercising a horse under saddle when they are experiencing hives. Sweat can exacerbate the physical discomfort around the bumps, while tack can further irritate the inflamed tissue. It is advisable to wait for a day or two for the hives to fully resolve before resuming regular work with your horse.

In the case of a one-time occurrence of hives in your horse, identifying the exact cause may be challenging. However, if hives become a recurring issue, it becomes important to pinpoint the allergen triggering the reaction. A proactive approach involves reflecting on recent changes in your horse's diet, environment, medications, vaccinations, or stress levels. By compiling a list of potential triggers and sharing it with your veterinarian, you can streamline the investigative process.

Effective management of hives in horses often revolves around minimizing exposure to potential allergens through ingestion, contact, or inhalation. Through careful observation and investigation, you can potentially uncover the root cause of the hives and take necessary steps to prevent future occurrences. By working collaboratively with your veterinarian and employing time-tested strategies, you can ensure the health and comfort of your horse.

Another option is allergy testing to pinpoint allergic sources such as pollens, molds, grasses, weeds, dust mites, insects, and farm plants. This method requires the horse to be off medications like steroids or antihistamines for a period of 10-30 days prior to testing. Once an antigen is identified, immunotherapy injections, also known as hyposensitization, can be administered to target the specific allergen. This process is gradual and should be sustained for a minimum of one year. By gradually administering small doses of allergy vaccine, the horse's immune system can build tolerance to the allergen, leading to reduced or no reaction upon re-exposure. This innovative approach aims to enhance equine well-being and mitigate allergic reactions effectively.

Mud Fever

Thu, 23 May 2024 19:43:03 GMT

Learn the causes, treatments, and how to prevent.

Mud fever (also known as pastern dermatitis, scratches, dew poisoning, greasy heel, or cracked heels) is a common skin condition that affects a horse’s lower legs. It can be caused by irritation, bacteria, or fungal infection. Here’s what you need to know about mud fever:

Causes and Risk Factors:

Bacteria: One of the most common causes is a bacteria called Dermatophilus congolensis, which lives naturally on the skin but can penetrate weakened skin.
Wet Conditions: Mud fever is more prevalent during wet winter months when the ground is muddy and conditions weaken the skin.
Other Factors: Photosensitivity, and chronic mange mites can exacerbate the condition.

Symptoms:

Crusty scabs on the heels or lower legs.
Broken or damaged skin.
Matted hair or patches of hair loss with red, raw skin underneath.
Discharge between the skin and scabs.
Heat, pain, and swelling in the lower limb.
In severe cases, lameness or cellulitis may occur.

Treatment:

Clip the hair away from the affected area.
Gently wash with an antibacterial or antifungal shampoo.
Pat the area dry and apply a topical treatment (as directed by your vet).
Keep the horse off wet pastures and in a clean, dry stall.
Use zinc-oxide-based cream to soften scabs and create a moisture barrier.

Prevention:

Keep footing dry in stalls and turnout areas.
Use dry bedding.
Avoid unnecessary washing of legs.
Keep legs dry
Maintain good hygiene
Limit exposure to wet or muddy conditions.

Timely detection and effective management are crucial for treating and preventing mud fever in horses. If you suspect mud fever, consult your veterinarian for accurate diagnosis and tailored treatment.

Equine Cushing's Disease: Part II

Fri, 26 Apr 2024 19:11:22 GMT

The TRH Stimulation Test

The equine TRH stimulation test is a diagnostic procedure we use to assess the function of the pituitary gland in horses suspected of having Equine Cushing's Disease (also known as Pituitary Pars Intermedia Dysfunction or PPID). PPID is a common endocrine disorder in older horses that results from dysfunction of the pituitary gland, leading to excessive production of certain hormones, particularly adrenocorticotropic hormone (ACTH). See our previous post for Part I.

Here's how the equine TRH stimulation test works:

1. Preparation: Before conducting the test, the horse is typically fasted from grain for a period of time to ensure accurate blood sampling and minimize the influence of recent feed intake on hormone levels. Access to hay and forage is allowed.

2. Administration of TRH: TRH, or thyrotropin-releasing hormone, is a hormone produced by the hypothalamus, a region of the brain that regulates various physiological processes, including hormone secretion by the pituitary gland. In the TRH stimulation test, a veterinarian administers a specific dose of synthetic TRH intravenously or intramuscularly to the horse.

3. Blood Sampling: Just prior to and following the administration of TRH, blood samples are collected from the horse at specific time intervals, typically at baseline (before TRH administration) and at designated time points after TRH administration, such as 10, 20, and 30 minutes.

4. Measurement of Hormone Levels: The blood samples collected during the test are analyzed to measure the concentration ACTH. ACTH is the hormone primarily associated with PPID, and its levels are often elevated in affected horses due to dysfunction of the pituitary gland.

5. Interpretation of Results: The equine TRH stimulation test helps veterinarians assess the pituitary gland's response to TRH stimulation. In horses with PPID, the pituitary gland may exhibit an exaggerated or prolonged release of ACTH in response to TRH administration compared to healthy horses. Elevated ACTH levels following TRH stimulation are indicative of pituitary dysfunction and support a diagnosis of PPID.

It's important to note that the equine TRH stimulation test is just one of several diagnostic tools used to evaluate horses suspected of having PPID. Veterinarians may also consider clinical signs, such as abnormal hair growth, excessive drinking and urination, lethargy, and laminitis when making a diagnosis of PPID and determining the appropriate treatment and management plan for affected horses.

Overall, the equine TRH stimulation test plays a valuable role in diagnosing PPID and guiding treatment decisions, helping veterinarians provide optimal care for horses affected by this common endocrine disorder. This test allows us to catch horse's in the early stages of Equine Cushing's Disease so that we can prevent the significant health problems caused by this disease.

Equine Cushing's Disease: Part I

Wed, 17 Apr 2024 14:39:06 GMT

Equine Cushing’s Disease , also called Pituitary Pars Intermedia Dysfunction (PPID) , is one of the most common hormonal disorders affecting horses and ponies. It is seen most often in older horses, but it can occur at any age. Understanding PPID is essential for early diagnosis, effective management, and preventing serious complications like laminitis.

This guide explains what Equine Cushing’s Disease is, how to recognize the signs, how it’s diagnosed, and how it’s managed—in plain language for horse owners.

What Is Equine Cushing’s Disease (PPID)?

Equine Cushing’s Disease is caused by a dysfunction of the pituitary gland , a small gland located at the base of the brain. The pituitary controls many important body functions, including:

Hormone production
Metabolism
Immune function
Stress response

In horses with PPID, the pituitary gland produces excess hormones , especially ACTH , which leads to increased cortisol levels. Over time, this hormonal imbalance affects nearly every system in the body and can significantly impact a horse’s health and comfort.

What Causes Equine Cushing’s Disease?

The exact cause of PPID is not fully understood, but it is linked to changes in how the brain regulates the pituitary gland, specifically within the hypothalamic-pituitary-adrenal (HPA) axis .

Several factors may increase a horse’s risk, including:

Advancing age
Genetic predisposition
Environmental influences
Breed susceptibility, with ponies, Morgans, and some smaller breeds appearing more prone

Signs and Symptoms of Equine Cushing’s Disease

Early detection is key. Some horses show subtle signs at first, while others develop obvious symptoms as the disease progresses.

Common Symptoms of PPID Include:

Long, thick, or curly hair coat that does not shed normally
Excessive sweating , especially under heavy hair
Increased drinking and urination
Muscle loss , especially along the topline
Lethargy and decreased performance
Pot-bellied appearance
Recurrent infections , such as hoof abscesses or respiratory issues

Laminitis and PPID

Laminitis is the most serious and potentially devastating complication of Equine Cushing’s Disease. Persistently elevated ACTH levels have a toxic effect on the laminae of the hoof, significantly increasing the risk of painful and recurrent laminitis episodes.

How Is Equine Cushing’s Disease Diagnosed?

Diagnosis is based on a combination of clinical signs and blood testing .

Common Diagnostic Tests:

ACTH Blood Test: Measures adrenocorticotropic hormone levels, which are often elevated in horses with PPID.
TRH Stimulation Test: A more sensitive and specific test that can detect early or subclinical PPID , even before obvious symptoms appear.

Your veterinarian will recommend the most appropriate test based on your horse’s age, symptoms, and time of year.

Managing Equine Cushing’s Disease

While there is no cure for PPID , proper management allows many horses to live long, comfortable, and active lives.

1. Medication

Prascend® (Pergolide) is the cornerstone of treatment.
Pergolide is a dopamine agonist that helps regulate hormone production and reduce clinical signs.
Dosage is adjusted based on symptoms and follow-up testing.

2. Diet Management

Feed a low-sugar, low-starch diet
Avoid high-carbohydrate feeds
Proper nutrition helps reduce insulin resistance and lowers laminitis risk

3. Exercise

Regular, appropriate exercise helps maintain muscle mass and overall health
Exercise plans should be tailored to the horse’s age and soundness

4. Ongoing Veterinary Care

Routine monitoring of ACTH levels
Regular dental, hoof, and general wellness care
Most veterinarians recommend ACTH testing at least once yearly , or more often if medication adjustments are needed

Living Well With Equine Cushing’s Disease

Equine Cushing’s Disease can feel overwhelming at first, but with early diagnosis, consistent treatment, and close veterinary partnership , affected horses can enjoy an excellent quality of life.

By learning to recognize the signs of PPID and staying proactive with management, horse owners play a vital role in protecting their horses from complications—especially laminitis—and supporting long-term health and comfort.

If you suspect your horse may have PPID or want to discuss testing options, consult your veterinarian to develop a personalized care plan.

Pasture Management

Mon, 18 Mar 2024 19:52:55 GMT

Pasture Management for Springtime Grass

After months of barren ground or snow covered fields, we are slowly starting to see the gorgeous signs of spring in New England once again. The horses are shedding and eagerly awaiting any chance they have to nibble some delicious green grass. Below we provide very helpful guidelines for the slow controlled introduction to keep our horses safe and healthy.

Horses that always live outside have the benefit of mother nature's slow introduction to grass as it grows through the first weeks of spring. Horses living in stalls with only partial day turnout have to be more strictly controlled in their introduction to pasture to prevent the serious trouble that can occur with too much fresh grass too quickly. Over indulgence in grass can result in gas colic and laminitis. So what can you do to protect your horse from the potential hazards of too much grass too quickly?

Here are guidelines to assist you in coming up with a pasture introduction plan:

Horses on 2-12 hours a day of pasture:

If you have limited pasture but still want your horse to reap the benefits of daily turnout you probably fall into this category. Most horses in a boarding situation with access to grass will be in this group. Take care to closely follow a pre-determined time scale of introduction for these horses. We recommend the following graduated schedule:

Days 1-3: 20 min/day

Days 4-6: 1hr/day

Days 6-9: 2 hrs/day

Days 10-12: 3 hrs/day

Day 13 and beyond: unlimited in horses who are not overweight or sensitive.

You can also use a grazing muzzle (see below) if you need to introduce pasture more rapidly. With a grazing muzzle you can add 20 min per day of turnout until on full turnout. Once on full turn out keep muzzle on for about a week then alternate every other day for a week then it should be safe to remove the grazing muzzle.

Horses living out 24/7, a field big enough for constant grazing all season:

These horses normally do fine by themselves. Nature gives its own slow introduction to new grass and horses graze as the grass grows and adapt on a day- to- day basis. These situations are far more common in geographical areas like in the western US where grazing lands are plentiful. If your grass begins to come up very quickly you may want to use a grazing muzzle for a week or two to slow your horse's grass consumption during this period of rapid grass growth.

The most important thing to remember is that grass is a great source of calories for your horse. For the hard keeper thoroughbred-type, this is a great way to bulk them up after a long winter. For the rest of us with hearty warmbloods or chubby ponies, we have to watch these horses very carefully. In addition to the introduction guidelines above, we recommend the easy keepers or over conditioned horses use a grazing muzzle to slow their intake of grass and thus calories. While you may think this is cruel you are really doing your horse a huge favor. They can still eat grass normally it simply reduces the amount of grass they eat in a given time. If your horse has EMS (Equine Metabolic Syndrome) or PPID (Cushing's) please consult NBEA Veterinarians to come up with a safe plan catered to your horse.

Study shows Shockwave treatment is effective for suspensory ligament disease

Thu, 31 Jan 2019 00:00:00 GMT

Suspensory ligament injuries are one of the most common soft tissue injuries we see in the sport horse. These injuries can be very frustrating. A recent study from Virginia Equine Imaging shows that Shockwave treatment can return these horses to their previous level of work faster than only rest and with similar results to surgery.

North Bridge Equine often uses shockwave as our first line treatment for proximal suspensory disease and we have seen very good results with this treatment.
