Internal Medicine Specialists are often called upon when there is a particularly challenging or difficult case, as they have an unmatched understanding of the body’s biological systems. And with two of the very best Internists in California caring for your dogs or cats, you couldn’t be in better hands.

Your family veterinarian has an understanding of all facets of your dog or cat. Like humans, when animals have illnesses that go behind the scope of their family veterinarian, they will be referred to a specialist. An internal medicine specialist works with the internal body systems, whether there are sudden or chronic signs, and regardless of the cause of disease (infection, cancer, degenerative, inflammatory, immune, or endocrine). Internal medicine emphasizes non-invasive diagnostic and treatment techniques. At MarQueen Emergency and Specialty our strengths are medical treatments and comprehensive care, devoted to your dog or cat’s overall health.

A veterinary internist (veterinary internal medicine specialist) is a veterinarian with advanced training in the area of veterinary internal medicine. To become a board-certified veterinary internal medicine specialist, you must complete an additional four years of training following graduation from a four-year veterinary school. The first year is called an internship and the next three years are called a residency. During this time, you are trained by other board-certified specialists in the intricacies of internal medicine. At the completion of your residency you are classified as “residency trained” but not board-certified. In order to become board-certified in veterinary internal medicine, you must submit credentials and have an original article published in a peer-reviewed journal. At the end of two years of residency, you may sit for an intense 8 hour examination called the qualifying examination. Once this examination has been passed, and after your third year of residency you are eligible to take the certifying examination. This is given over a two-day period and involves essay questions, a practical examination, and multiple choice and short answer portions. After successful completion of this examination, you are considered a board-certified specialist in veterinary internal medicine by the American College of Veterinary Internal Medicine.

Common reasons to seek a veterinary internist

  • Immune mediated (auto-immune) and inflammatory conditions, such as Addison’s Disease, IMHA, ITP, pancreatitis, hepatitis, and bronchitis.
  • Liver Shunt
  • Tick-Borne Diseases such as Lyme Disease
  • Infectious disorders such as Leptospirosis
  • Diabetes
  • Some cancers such as lymphoma and melanoma

*There is also a myriad of disorders that are often masked as some of the diseases mentioned above and can be tricky if not treated by a specialist – in some cases, the longer the incorrect diagnosis the less chance for long-term recovery or survival.

Our internal medicine specialists also utilize state of the art endoscopy system that allows them to perform minimally invasive biopsies and foreign body removals. A simple out patient procedure requiring little recovery time allows the patient to go home that same day.
