Veterinary Internal Medicine

You’ll find that your board certified internist may rely on a wide array of tests to ascertain the cause of your pet’s illness – including digital radiography, endoscopy and ultrasound.

With ultrasound, your pet benefits from a painless, non-invasive method of examining internal organs and determining whether further medical action is needed. Used in combination with radiology, it can form a highly-effective means of identifying and treating specific health conditions.

Your pet also benefits from the collective experience and expertise of our assembled veterinary team. When necessary, our internists are supported in making their diagnoses by other pet specialists at Columbia River VetERinary Specialists. Types of cases include:

  • Acute Heart Failure
  • Arrhythmias
  • Cardiac Emergencies
  • Addison’s Disease
  • Intensive Care Monitoring
  • Complicated and Atypical Cushing’s Syndrome
  • Complicated Diabetes Mellitus
  • Chronic and Acute Renal Failure
