Veterinary Internal Medicine

Internal medicine is a term used to describe a variety of specializations that focus on the prevention, diagnosis, and treatment of diseases in animals. Our animal internal medicine practitioners specialize in dogs, cats, exotic pets, and reptiles, and can help with both alleviation of symptoms and treatment of diseases, disorders, or birth defects. If you have been referred to us by another veterinarian, or if you believe your pet is suffering from a disease, please make an appointment below.

Appointments

Once you have consulted with your primary care veterinarian and they have referred your pet to our Internal Medicine specialist, you can call Monday through Friday 8:00 am - 5:00 pm to schedule an appointment. If our coordinator is unavailable at those times, you may be asked to leave your name and phone number so we can schedule an appointment.

For the safety of all hospital patients, all dogs and cats must be leashed, crated or carried at all times. Retractable leashes must be locked at all times. Appointments/consultations are approximately 60 minutes, depending on the severity of the case. Our internist will review the medical record and speak to you about the ongoing issues. In most cases, an abdominal ultrasound will be performed during the consult.
