Equine Internal Medicine

About the Service

The Equine Internal Medicine service specializes in the diagnosis and treatment of horses with a variety of clinical conditions. The service provides diagnostic evaluations, hospitalization, and intensive care management of horses needing 24-hour therapy, diagnosis and treatment of emergency conditions, and routine preventative health care. The aim of the equine internal medicine service is to provide the horses with outstanding care and to provide their owners with compassionate, exceptional service.

What We Do

The Equine Internal Medicine service evaluates horses with a variety of clinical conditions. These include, but are not limited to, diseases of the respiratory tract such as pneumonia, recurrent airway obstruction (RAO or heaves), and exercise induced pulmonary hemorrhage (EIPH); neurological abnormalities such as wobbler’s syndrome and equine protozoal myeloencephalitis (EPM); gastrointestinal diseases such as colic, diarrhea, equine gastric ulcer syndrome (EGUS), and weight loss; endocrine conditions such as equine metabolic syndrome (EMS) and Pituitary Pars Intermedia Dysfunction (PPID, or Equine Cushing’s syndrome); neonatal foal care; and many more. Additionally, the Equine Internal Medicine service works closely with the board certified specialists of the ophthalmology, cardiology, dermatology, and oncology services to diagnose and treat diseases of the equine eye, heart, and skin, and to treat various equine cancers. The Equine Internal Medicine service also performs routine preventative health care including vaccination, health certificates, Coggins testing, deworming, and dental care.

The Equine Internal Medicine service has access to state-of-the-art equipment for use in equine patients. This includes digital radiography, video endoscopy, ultrasonography, computed tomography (CT), magnetic resonance imaging (MRI), radiation therapy (linear accelerator), electrocardiogram, and echocardiography.

Who We Are

The Equine Internal Medicine service is composed of three faculty who are board certified specialists in large animal internal medicine that work on the service. Additionally, the service has three resident veterinarians who are training to become specialists. The service has two dedicated veterinary technicians who assist the veterinarians to manage day to day operations. Senior level veterinary students of the college work with the veterinarians to diagnosis and treat horses in our care.
