What is a veterinary internal medicine specialist? 

A board-certified or board-eligible internal medicine specialist is a veterinarian who has completed advanced training following four years of veterinary school, including a one-year internship followed by a three-year residency. Board-certification involves successful completion of a rigorous comprehensive examination and publication in a peer-reviewed medical journal. Following successful completion of these qualifying steps, the doctor is granted "Diplomate" status and is considered a board-certified specialist in Internal Medicine.  

Why does my pet need an internal medicine specialist? 

If your pet is experiencing particularly complicated, chronic, or recurrent medical issues, your general practitioner may refer your pet to a specialist in internal medicine. When baseline diagnostic testing does not reveal the cause of your pet's condition, advanced testing might be required in order to obtain an accurate diagnosis and develop a targeted and effective treatment plan. Internists are trained to understand the interactions of all internal organs, and how to safely and effectively treat the underlying cause of your pet's disease safely and effectively. Specialists in internal medicine partner with both the pet owner as well as the patient's primary care veterinarian to monitor the long-term health and recovery of your loved one.
