What is a Veterinary Internist?

A Board-certified Veterinary Internist has undergone extensive training for certification by the American College of Veterinary Internal Medicine (ACVIM). In addition to undergraduate training and four years of veterinary school, specialists are required to complete a one-year internship and 3 year (minimum) residency in their area of specialty. Furthermore, extremely thorough and exhaustive examinations must be passed in order to achieve certification. A Veterinary Internist has been trained to diagnose severe, chronic illnesses and other complicated conditions consisting of multiple problems. They generally treat a variety of problems involving the numerous body systems: gastrointestinal, infectious disease, respiratory, urologic, immune-mediated and hematologic, and endocrinopathies.

Why should my pet see a veterinary internist?

Your pet would benefit from seeing an Internist if they have an uncommon or undiagnosed disease process after standard testing has been performed with your family Veterinarian. Your pet may also be referred if he/she has multiple problems that are difficult to manage. Referral is also recommended if your pet has a diagnosis, but the typical treatments for that disease process are not going as planned. Our hospital offers sophisticated procedures by skilled doctors, in addition to exceptional patient care in our 24-hour intensive care unit.

What should I expect at the initial consult?

At your pet's initial consult, their vital signs and a physical examination will be performed. It is very important for you to bring all of your pet's medical records, any x-rays that have been taken, and their current medications. Once the doctor has reviewed the medical records, the medical history, disease processes involved, and any further recommended testing and/or treatments will be discussed fully.

Pets coming in for consultation should be fasted. This means no food for 12 hours before their appointment. If your pet is diabetic, please call the office and ask for special instructions regarding specific fasting recommendations prior to their appointment.

Please also please come in to our clinic at least 15 minutes prior to your scheduled appointment time in order to fill out the necessary paperwork.

Please contact us to schedule an appointment. We are available to answer any questions or concerns you may have regarding your pet’s health.
