Equine Internal Medicine Service

Internal medicine is a specialty that focuses on the diagnosis and treatment of diseases and complex systemic disorders affecting the horse.

The Internal Medicine Service offers consultations for a wide range of medical conditions and works closely with other services such medical imaging, surgery, anesthesiology or theriogenology as well as with the Diagnostics Service of the Faculté de médecine vétérinaire to enable quick and accurate results.

The Internal Medicine team consists of specialists certified by the American College of Veterinary Internal Medicine. Our specialists are recognized worldwide for their expertise in their field of practice and contribute to the advancement of knowledge in equine health by their research.

The neonatal intensive care unit receives more than a hundred foals per year, most accompanied by their mother. Because every minute counts, our team is available to receive emergencies 24 hours a day, 365 days a year.

Many reasons can lead the client to consult our team, monitoring high-risk pregnancies or during early foaling, neonatal infections, neonatal maladjustment, orphan foals, contagious diseases or other. The neonatology unit works with specialists from various services throughout the Equine Hospital to provide primary care at the highest level to the foal and mother.
