Internal Medicine

The specialty of small animal internal medicine is broad in scope and focuses on the treatment of numerous organs and body systems. Diagnosing some of these conditions can be a challenge because many pets experience a variety of symptoms which can be indicative of multiple diseases. This is why you sometimes hear internists called puzzle solvers. Their diagnostic skills and treatment acumen must be extremely acute in order to determine the precise cause of the problem.

Our internists perform advanced diagnostic and therapeutic procedures including:


  • Rhinoscopy
  • Bronchoscopy
  • Bronchoalveolar lavage
  • Tracheal wash


  • Diagnostic testing/diabetes mellitus
  • Cushing's disease
  • Thyroid disorders


  • Blood transfusion therapy
  • Bone marrow aspirates


  • Endoscopy for biopsy of intestines, stomach,
    colon, retrieval of foreign bodies
  • Feeding tube placement  

Autoimmune Diseases

  • Hemolytic Anemia
  • Thrombocytopenia
  • Polyarthritis

  • Digital radiography (x-ray)
  • Ultrasound
  • Fluoroscopy
  • Computed tomography (CT Scan)
  • Ultrasound guided aspiration and biopsy
