Dr. Phillip Ryan is originally from Grosse Pointe, Michigan. He is a veteran of the United States Navy and served two tours of duty in the Persian Gulf as an Operations Specialist and Search and Rescue swimmer. After the military he studied biology at the University of Michigan while working in the research fields of endocrinology and cardiothoracic surgery. He then attended Michigan State University for veterinary school followed by a small animal medicine and surgery internship at the University of Wisconsin. He spent a year working as an emergency veterinarian followed by a year as a primary care veterinarian before realizing that his true passion was internal medicine. He completed his small animal internal medicine residency at the University of Tennessee.

His areas of interest include immune-mediated diseases, hyperadrenocorticism, blood disorders, acute and chronic kidney diseases, chronic inflammatory enteropathies, and minimally invasive procedures such as endoscopy, laparoscopy, joint taps and bone marrows. Dr. Ryan loves all of his patients but is especially fond of giant-breed dogs. He is eager and excited to establish a supportive and collaborative relationship with primary-care veterinarians in New Hampshire.

What Is a Veterinarian Who is Residency Trained in Internal Medicine?

A doctor that is Residency trained in internal medicine is a licensed veterinarian who has obtained intensive, additional training in understanding how your pet's internal body systems function and in diagnosing and treating the many serious diseases that can affect the health of those systems. They will have advanced training in the following disciplines:

  • Endocrinology
  • Cardiology
  • Gastroenterology
  • Hematology (study of the blood)
  • Immunology
  • Infectious Diseases
  • Nephrology/Urology
  • Respiratory Diseases
  • Hepatology (Liver Disease)

While your general practitioner veterinarian can diagnose and treat many health problems, certain diseases and conditions require the care of a doctor who has had specialized, intensive training in internal medicine in order to provide the very best outcome for your pet.

Within the discipline of veterinary internal medicine, there are also veterinarians who specialize further in Small Animal Medicine, Cardiology, Neurology, and Oncology.

Why Does My Pet Need A Doctor That is Residency Trained in Internal Medicine?

Just as your own primary care physician may feel the need to refer you to the care of a specialist from time to time, your general practitioner veterinarian may feel your pet needs a veterinarian with addition training to help diagnose or treat a particularly complicated medical problem. While your general practitioner veterinarian can handle many aspects of your pet's care, just as in human medicine, there is sometimes a need for the attention of a doctor with additional expertise. You can be assured that a veterinarian who knows when to refer you and your pet for more specialized diagnostic work or treatment is one that is caring and committed to ensuring that your pet receives the highest standard of medical care for his or her problem.

While in some cases, your veterinarian may be able to simply consult with a residency trained doctor about your pet's care, in other cases it is necessary to actually refer you and your pet to this doctor for more advanced diagnostics and treatment. Residency trained doctors may also have access to specialized diagnostic or treatment tools that a general practitioner veterinarian may not have.

What Health Problems Does a Veterinarian That is Residency Trained in Internal Medicine Treat?

These doctors are trained to treat the most serious diseases and health problems that affect pets. They are also especially prepared to care for pets that may be facing multiple health problems. Thanks to better health care, more and more pets are living longer lives. As a result, an increasing number of older pets, just like older people, are coping with multiple disease states that can be very difficult to manage. For example, a cat with diabetes may also be suffering from kidney failure, or a dog in heart failure may also be diagnosed with cancer. These veterinarians are uniquely prepared to oversee the care of these complicated cases. In other situations, a younger animal may develop a problem that used to be considered untreatable but is now manageable and perhaps even curable.

Here are some common diseases that frequently lead general practitioner veterinarians and concerned pet owners to seek the expertise of a residency trained veterinarian:

  • Cancer
  • Heart Disease
  • Gastrointestinal Diseases
  • Diabetes Mellitus
  • Immune Related Disorders
  • Kidney Dysfunction
  • Hyperadrenocorticism (Cushing’s disease)
  • Hyperthyroidism
  • Lower Urinary Tract Disease

Will My Regular Veterinarian Still Be Involved?

In many cases, your regular veterinarian will still supervise your pet's veterinary care, especially if your pet is coping with multiple disease states or conditions. In other cases, your referral doctor will take over the majority of your pet's medical care. It depends on your pet's particular disease and health problem.
