Common Veterinary Diseases of Companion Animals

Common Veterinary Diseases


There are a variety of common veterinary diseases, many of which mimic those in people.  Dogs and cats (companion animals) suffer from a range of diseases and disorders, which often require treatment with veterinary drugs, devices, biologics, supplements, special diets, etc.

Listed below are some of the common veterinary diseases and reasons for dogs and cats presenting to veterinary hospitals for treatment.  Many of these conditions and diseases are very similar to human diseases, and many of the same treatments are used in dogs and cats as they are in people.

  • Musculoskeletal and orthopedic disease
  • Dental disease and periodontal disease
  • Gastrointestinal tract, hepatic and pancreatic disease
  • Cardiac disease such as congestive heart failure
  • Lower urinary tract and kidney disease
  • Ocular diseases such as cataracts and dry eye
  • Neurologic and spinal cord disease
  • Infectious disease (bacterial, fungal, viral)
  • Cancer and neoplastic disease
  • Dermatologic disease including atopy and allergic dermatitis
  • Ear disease including infections
  • Endocrine diseases such as diabetes and thyroid disorders
  • Respiratory tract disease
  • Obesity
  • Behaviorial problems including phobias and separation anxiety

Comparative and Translational Medicine (Quick Link-Veterinary Clinical Trials)

Watch the video below, which illustrates why studying canine diseases such as cancer can benefit people and pets.  In addition to cancer, dogs also develop a range of orthopedic, dermatological, ophthalmic, autoimmune, immune mediated, gastrointestinal, and other conditions which are comparative to humans.  This similarity in patho-physiology allows researchers to study veterinary diseases which can lead to treatments for veterinary and human medicine.
