Neonatal intensive care

Our faculty and staff are highly experienced in managing the variety of disorders that may affect the neonatal foal or other large animal. Our specially designed Neonatal Intensive Care Unit is designed to accommodate the special needs of the critically ill neonate as well as pregnant animals at increased risk for complications around birth.

Contagious diseases

Our faculty and staff are experienced in diagnosing and managing a wide variety of contagious diseases. Our isolation facilities and procedures allow for the separation of horses and other large animals that have a contagious disease such as salmonella, or equine influenza. These separate facilities protect other patients in the hospital and also allow for intensive care of the patient to continue unhindered.

We offer the latest in diagnostic and treatment options for problems such as colic, colitis (diarrhea), gastric ulcers, chronic inflammatory bowel disease, weight loss, or poor appetite. Capabilities include a 3 ½ meter gastroscope, ultrasound examination performed by experienced clinicians and intestinal absorption studies.

Respiratory diseases

Our veterinarians diagnose and treat infectious and allergic diseases using advanced equipment and diagnostic procedures such as endoscopy, tracheal or bronchoalveolar lavage, bacterial culture, virus isolation, and/or skin testing. We can evaluate horses for laryngeal dysfunction (“roarers”) using our dynamic (over ground) endoscope, while being ridden in the area or on a high speed treadmill. Oxygen, nebulization and other inhalation therapies are available.

Cardiac diseases

We collaborate with board certified cardiologists to provide state of the art assessments and therapy for heart murmurs, exercise intolerance and arrhythmias. Diagnostic capabilities include echocardiographic assessment, ECG monitoring under exercise, 24 hour Holter monitoring and exercise stress testing.

Neurologic diseases

We evaluate, diagnose and treat large animal patients with a wide variety of neurologic conditions such as Wobblers syndrome, headshaking and seizures. Signs of a neurological problem include neck or back pain, issues with balance, muscle atrophy, weakness, tremors, difficulty swallowing, deafness or blindness. We offer a broad range of diagnostic capabilities including spinal taps, EPM testing, radiography, myelograms, CT, MRI and muscle biopsy.

Tying-up and other muscle diseases

Our faculty have experience diagnosing a wide variety of muscle disorders. A full examination may include exercise testing, muscle biopsy evaluation and genetic testing.

Wellness examinations for older horses

We can provide routine, in-depth health evaluations for problems seen in older horses such as dental abnormalities, pars pituitary intermedia dysfunction (PPID or equine Cushing’s disease), and weight loss.

Other medical conditions

In addition to the conditions mentioned above, we also provide evaluations for endocrinopathies, such as equine metabolic syndrome (EMS), skin disorders, laminitis and nutrition concerns. We are uniquely qualified to examine, diagnose, and treat a wide variety of complex conditions that may involve more than one organ system or require a multifaceted approach.

Our evaluations are thorough and can take time. You may want to bring a good book or electronic device (wireless is available in the lobby).

If necessary animals can be dropped off the morning of, or the night before and trailer parking is available.
