A veterinary internal medicine specialist is a veterinarian who completes a residency program in internal medicine after a rigorous selection process and is board certified through examination by the American College of Veterinary Internal Medicine (ACVIM). The ACVIM is sanctioned and supported by the American Veterinary Medical Association (AVMA).

The residency program for an internal medicine specialist candidate includes training and supervision by board certified specialists and focused classroom training. Residents are trained in managing difficult or complicated medical cases, providing advanced diagnostic procedures and tests, and interpreting test results in conjunction with a patient’s clinical signs.

Residents who have completed the program are proficient in a variety of medical conditions including gastrointestinal diseases, renal diseases, liver diseases, endocrine diseases, immune mediated diseases, infectious diseases, cardiac diseases, respiratory diseases, neurological diseases, and oncologic diseases. Some residents may choose to further specialize in areas such as neurology, cardiology, or oncology.
