Colonoscopy for Dogs

A colonoscopy is a diagnostic test that is run on the large bowel of a dog to investigate serious and possible life-threatening symptoms. The colonoscope is a flexible, lighted, tubular instrument that lets the veterinarian see inside the colon. Anesthesia keeps the dog calm and safely immobile.

  1. Function

    • Symptoms including chronic diarrhea, discomfort, constipation and general ill health may be reasons for a colonoscopy. A dog is given a preparatory solution to cleanse the bowel thoroughly before the colonoscopy is performed. Enemas may also be used to cleanse the bowel.

    Procedure

    • Air is introduced to the bowel, enabling the veterinary surgeon to insert a flexible scope into the rectum of the dog. The colonoscope is inserted into the bowel unless an obstruction blocks the way. For example, an obstruction can be a foreign object the dog has swallowed, or a tumor. Biopsies are taken with small forceps for further testing.

    Results and Complications

    • Medical issues can be diagnosed with a colonoscopy. The dog may be further treated for colitis or cancer due to the test results. Colonoscopy procedures have minimal complications, including rare perforation of the bowel and anesthesia problems.
