Soundness You Can trust: From The Schooling Ring To The Grand Prix Ring
Schedule a performance-focused gait assessment
At Metamora Equine, our veterinarians in Farmington Hills, Michigan provide veterinary services to communities in Oakland County, surrounding regions, and throughout the state. We bring board-certified equine sports medicine and advanced diagnostics directly to your barn, finding problems before they reach the point of reshaping your horse’s movement, behavior, and training for months. A horse that’s carrying a problem isn’t always a horse that looks hurt. The most damaging conditions in performance horses, low-grade lameness, subclinical gastric disease, restricted airway function, often leave no visible signs until they’ve already shaped movement, behavior, and training for months.





Metamora Equine delivers advanced, performance-focused veterinary care for competition horses, led by Dr. Thaler’s board-certified expertise in equine sports medicine. Every service supports accurate diagnosis, long-term athletic success, and thoughtful treatment.
We provide exceptional care for your equine athlete. Metamora Equine brings evidence-based medical solutions to the stall. We leverage technology and 40 years of experience to deliver health care to your horse.
Comprehensive care: working with your trainer, your farrier and you to provide the optimum performance management for your horse.

Dr. Thaler graduated from the University of Pennsylvania School of Veterinary Medicine and has spent the decades since building one of the country’s more credentialed ambulatory equine sports medicine practices. The DACVSMR board certification covers the full clinical scope of what this practice does: diagnosing and managing conditions that limit athletic horses. His Fellowship in the College of Animal Chiropractors and certified membership in the International Society of Equine Locomotor Pathologists extend that scope into spinal function and locomotor pathology in ways that most general practitioners don’t have training in. He has served as an adjunct professor at Michigan State University’s College of Veterinary Medicine, sits on industry advisory boards, and contributes to the publications that shape how the field approaches performance horse care. In the field, he works alongside Bonnie Thaler, a certified veterinary technician and core support staff member who handles client coordination and hands-on evaluation support at every visit. Dr. Thaler is frequently the practitioner that other equine veterinarians contact when a performance case isn’t resolving.
Horse people develop an instinct for when something is off, but instinct doesn’t tell you where the problem is or how significant it has become. These sections explain who belongs in a lameness evaluation, what the process looks like, and what research shows about the cost of waiting.
The stride feels slightly different. The horse is swapping leads more than before. A movement that used to be automatic has developed hesitation. These observations are almost always right that something has changed, but pinpointing the source requires more than observation. That is what professional lameness evaluation is built to provide.
Any horse competing at a level where gait quality affects results deserves regular lameness screening, not just evaluation after something goes wrong. Dressage horses where collection and impulsion have become uneven, hunter/jumper horses chipping distances or tightening over fences, and event horses refusing combinations they’ve jumped for years all warrant evaluation. So do horses returning to work after any significant layoff, horses going through a pre-purchase process, and horses whose riders or trainers have noticed a change they can’t tie to anything specific. Young horses entering intensive training benefit from an early baseline before training demands escalate.
The evaluation builds from observation to localization to confirmation. We watch your horse at multiple gaits on straight lines and circles, then bring in the Arioneo Vet Equisym System to quantify what observation suggests and catch what it misses. Flexion tests stress specific joints and narrow the region of interest. Diagnostic blocks then confirm the pain source by eliminating candidate structures until movement improves measurably. Digital radiography and ultrasound give us the structural detail we need once we know exactly where to look.
Lameness evaluation is the document that makes everything else in your horse’s care deliberate rather than reactive. The findings tell your farrier which hoof balance adjustments support soundness. They tell your trainer which movements protect the horse during recovery. They give your referring veterinarian the baseline needed to track change over time. And they give you, with data rather than assumption, a clear and accurate picture of what your horse’s actual situation is.
The right time is before a problem has a competition result attached to it. A rider’s note about a subtle change at the end of last season, a trainer’s observation that the canter feels different on one lead, a horse that came back from rest less forward than expected: these are all appropriate triggers. Pre-purchase evaluation, pre-season screening, routine exams, and post-injury clearance all belong in a lameness assessment schedule, not just the horse that pulls up obviously unsound.
The human eye has a documented detection limit when it comes to equine gait asymmetry, and mild hindlimb lameness is precisely where that limit matters most. Research published in the Equine Veterinary Journal demonstrated that for this category of lameness, “a sensitivity of 89% was achieved with a specificity of 75%” using objective inertial sensor gait analysis, putting a measurable number on what professional diagnostic tools catch that hands and eyes miss. Meeting the highest standards of care in lameness diagnosis means moving beyond visual assessment to objective, quantified evaluation. The horses that arrive at evaluation with earlier-stage findings have more treatment options available. The ones that arrive after months of continued training on an undiagnosed problem have fewer.
The horse that keeps training on an undiagnosed lameness doesn’t hold steady. The original structure continues to load abnormally, compensation shifts weight to other limbs and joints, and a single-source problem becomes a multi-structure problem over weeks and months. Research published in Animals tracking musculoskeletal injuries in event horses found that horses were “out of training for the most amount of time (>12 months)” with deep digital flexor tendon injuries, the kind of soft tissue condition that worsens specifically under continued training load. Scar tissue that forms from unmanaged damage doesn’t function like healthy tissue, and horses that miss their early intervention window often carry those structural limitations for the rest of their careers.


When a horse isn’t producing at the level everything around them should be generating, the answer is almost never in the training program. These sections explain who needs this evaluation, what it covers, and why adjusting training before making a diagnosis is the wrong sequence.
Your horse has been working consistently and the training program is solid. The scores have dropped anyway. Or the feel under saddle has shifted in a way no one can point to specifically. Performance assessment exists for exactly this situation: not the horse with an obvious physical problem, but the one where the gap between expected and actual output has no clear explanation yet.
The difference between a competition horse that stays sound through a long career and one that doesn’t often comes down to whether care addresses the specific demands of their sport, or just health in general. These sections cover who benefits from sports medicine oversight, how it works alongside training, and what happens to horses that compete without it.
A sport horse’s medical needs don’t map neatly onto the approach built for the broader equine population. The stresses of competitive training, frequent travel, high-intensity work, and discipline-specific biomechanical demands require a care model that accounts for those specifics rather than treating the horse like a healthier version of an average patient.
Every horse on a regular competition schedule benefits from sports medicine oversight, but the need is most acute in specific situations. Young horses entering their first competitive seasons need conditioning protocols that build fitness without creating the overuse patterns that cause breakdown early in a career. Horses competing frequently or traveling between venues accumulate physical load in patterns that general practice isn’t calibrated to monitor. Horses with any previous injury, even one that appeared to fully resolve, carry structural vulnerability that a sports medicine program actively manages rather than waits on. Older competition horses need maintenance programs that extend competitive years, protect quality of life, and manage decline actively rather than reactively.
A sports medicine program is built around your horse’s specific discipline, competition schedule, and history rather than a fixed protocol. Spinal manipulative therapy maintains vertebral alignment that intensive training consistently disrupts. Diagnostic imaging monitors structural areas of concern before they develop into sources of lameness. Wellness exams and laboratory work track fitness and health markers that shift across training cycles. Regular objective gait analysis with the Arioneo Vet Equisym System captures movement trends over time so small changes are identified before they compound. Treatment protocols address the specific physical stresses that each discipline places on different structures.
Sports medicine runs parallel to your training program rather than responding to breakdowns within it. Therapeutic interventions are scheduled around your competition calendar so your horse arrives at major events at their best rather than recovering from treatment during them. Findings from regular monitoring give your farrier, trainer, and referring veterinarian shared, current information rather than each working from a partial picture. This coordination produces better continuity of care across all the professionals involved in keeping your horse competitive.
The most productive entry point is before the first competition season, not after the first injury. This is preventive care at its most effective: establishing a baseline when a horse is healthy gives you something to measure future changes against, making early detection possible rather than reactive. For horses already competing, a pre-season evaluation before the schedule begins captures the current state and identifies any developing issues before training and competition load intensifies. For horses in the middle of a competitive year, the right time to engage in a sports medicine program is when you recognize the need for one.
General veterinary care for horses is built around the broad middle of the horse population. Sport horse medicine is calibrated to the far end of it, and the gap between those two populations is wider than most people expect. Research published in Animals from the University of Milan’s Equine Sports Medicine Laboratory confirmed that “poorly performing horses are mostly normal on physical examination,” meaning the primary assessment tool that general practice uses doesn’t catch the conditions that are actually limiting athletic horses. Sports medicine brings the dynamic testing, discipline-specific clinical context, and the diagnostic scope that a standard examination doesn’t include.
The career consequences of competing without sports medicine monitoring rarely look like a single catastrophic breakdown. They look like a series of smaller setbacks that progressively narrow what the horse can do. Research published in Animals from the University of Milan’s Equine Sports Medicine Laboratory found that horses competing with undiagnosed lower airway inflammation experienced “a shorter and less successful career” compared to those who received proper evaluation and targeted treatment. That finding captures something owners of high-mileage competition horses recognize intuitively: the horse that keeps competing without adequate oversight doesn’t arrive at a definitive endpoint. The career just gets shorter, and each limitation that accumulates makes the next one harder to address.


40+ years of experience. National reputation. Proven clinical and business leadership.




Metamora has really great imaging that they bring right to us. It allows them to follow every lead to fruition. No waiting and no guessing. They also take a very methodical approach to every exam. It’s a process, like building a puzzle, so using diagnostics and technology to collect data reveals another part of the puzzle.
Sarah Ash, Trainer, True Course Farm
Doctor Thaler is incredible at diagnostics. He has the tools, the training, and the experience to solve challenges that other vets really could not. Figuring out lameness can be very subjective. Dr. Thaler uses technology to look for answers and tell him things that the rider can’t, that the horse can’t.
Cindy Petherbridge, Trainer, Huntsover Farms
With Metamora, the horse comes first. They bring urgency and care to every visit. They’re good with the horses – even difficult ones – and then they take the time to talk to the owner or the rider.
The technology has always been the thing that impressed us. Doctor Thaler has the science that backs it up. He has the tools and the techniques, and he’s done the studies and read the latest news. When he makes a suggestion, there are facts behind it, not a guess. He gives you the best of all the options available for whatever we are dealing with.
Rhonda Wille, Owner
It’s easy for vets who see hundreds of horses to quickly turn to solutions that have worked for them before. In contrast, Dr. Thaler is always gaining new knowledge. He has the most modern and best diagnostic equipment, and so he suggests new perspectives and ideas. That’s important to being successful in diagnosing injuries and problems.
For clients serious about performance, Metamora is my go-to. Dr. Thaler is the top sports veterinarian and a partner and resource for diagnosing lameness and other problems, as well as suggesting therapeutic solutions.
Garth Short, Owner, Horseshoeing Incorporated
The communication from Metamora is key. I am always contacting them first with my questions. They’re ability to answer the call and provide service to clients is unmatched, even if that means going the extra mile to accommodate.
Leah Smaller, Professional Rider and Trainer
Doctor Thaler has a problem-solving mindset. There’s no one better at finding an issue. He uses technology and experience to understand the issue.
Jaafar Reza, Trainer, Gross Point Equestrian
There are many different therapeutic applications that promote healing. Dr. Thaler comes in with the science. He’ll study the X-rays and do the diagnostics, then I’ll do the farrier work. We’ve brought horses back from lameness and saved horses that otherwise would be done. He’s 100% onboard to get the horse through it.
This practice defines excellence
Dana Wille, Head Trainer, Equine Odyssey
Sometimes I walk into a barn and know Metamora’s been there because there is a picture drawn of a horse’s leg showing where this injury was. Dr. Thaler is great at explaining complex things very simply.

Farmington Hills horse owners bring serious competitive ambitions to their programs, and the veterinarians in Farmington Hills, Michigan they work with should bring the same depth of preparation. Whether the question is a gait change that needs objective evaluation, a performance decline that needs multi-system assessment, or an ongoing sports medicine program for a horse competing at a high level, Dr. Thaler and Metamora Equine deliver that level of care at your barn. Don’t wait for a small problem to define itself by getting larger, call Metamora Equine today at 248.310.5568.

Common questions from Farmington Hills area clients about how to get started, what a first visit looks like, where we travel, and how we fit into your horse’s existing care.
Two to three weeks is a workable window for planned evaluations during most of the year. During peak spring and fall competition seasons, earlier booking gives you better options. For emergency care situations or acute cases that can’t wait, call us directly rather than booking through the standard form. Bonnie Thaler manages all scheduling and will give you an honest read on current availability and what we can do to accommodate urgent cases.
Dr. Thaler opens every visit with a detailed conversation about your horse’s history before the examination begins, because that context shapes which parts of the workup deserve the most attention. Hands-on evaluation and movement assessment follow, with diagnostic procedures added based on what the findings call for. Before the visit ends, you will receive a plain-language summary of what was found, what it means for your horse, and a clear recommended next step. No open-ended questions left on the table.
The practice is fully ambulatory. Dr. Thaler travels to your facility with the diagnostic equipment the case requires, including the Arioneo Vet Equisym objective gait analysis system, an on-site x-ray machine for digital radiography, and ultrasound. Assessing horses in their home environment produces more representative findings than a veterinary clinic visit in an unfamiliar setting, and it removes the travel stress that changes how a horse moves and presents. We serve Farmington Hills and the broader Northwest Detroit region as a regular part of our Michigan circuit. For cases requiring advanced imaging such as MRI, CT, or nuclear scintigraphy, or situations where critical care at an animal hospital becomes necessary, we coordinate with those facilities and stay involved throughout rather than stepping away from the case.
After each visit, Dr. Thaler provides a written findings summary that goes directly to your primary veterinarian so everyone involved in your horse’s care is working from the same information. For horses with complex or ongoing cases, we stay in contact with referring vets through the treatment process rather than handing off at the end of a single visit. The goal is to add the sports medicine and diagnostic depth that general practice isn’t structured to provide, not to replace the veterinary relationship your horse already has.
The combination of credentials, focus, and commitment to standards of care is difficult to find in an ambulatory practice. Board certification through the American College of Veterinary Sports Medicine and Rehabilitation, Fellowship in the College of Animal Chiropractors, and certification with the International Society of Equine Locomotor Pathologists cover a clinical range that most practitioners don’t have collectively. Metamora Equine has operated since 1999, and the depth of veterinary experience in performance horse cases over that time doesn’t translate from a generalist background. The horses that come to us are frequently the ones that have already been through a standard workup somewhere else and still don’t have answers.
