Inflammation of the colon or rectum can occur in different degrees that range in determining how uncomfortable your pet will be. In any case, if your dog is having issues with inflammation, it is necessary to make an appointment with the veterinarian in order to pinpoint the cause. Some of the causes for colitis and proctitis (such as ingestion of contaminated food, invasion of parasites, or cancer) can lead to long-term damage if left untreated. Treatment can range from simple medication therapy to surgery. Depending on the cause for the inflammation, the prognosis can vary from excellent to poor. Because of the variation in severity, a complete physical check-up for your pet is highly recommended if the bowel movements are abnormal for longer than a day or two.

Colonic and rectal inflammation are medically defined as colitis and proctitis respectively. When a canine has inflammation in either area he may suffer acute or chronic episodes of diarrhea. In some instances, dogs will strain to defecate and pass only a small amount of stool with the bowel movement.

The signs of inflammation apparent in one dog to the next can be different. No matter what the symptoms, as a pet owner you will know that your dog is having a problem as his behavior will very likely reflect his discomfort.

Some dogs will have additional symptoms of vomiting, weight loss, lethargy, and dehydration, depending on the illness.

Inflammation of the colon (colitis) or rectum (proctitis) can be chronic, which means that it is a continual problem, or acute, whereby it comes on suddenly. In addition, there is the instance of chronic episodic colitis and proctitis, which is intermittent recurring events of inflammation.

When the colon or rectum are inflamed, there is an inadequate absorption of water and a thickening of the colon. The rectum can also have fistulas, which are openings and lesions that progressively worsen causing great pain, especially when a dog attempts to have a bowel movement.

The clinical signs seen by the physical examination will be a part of the diagnostic process, but information that you can provide first hand will prove to be invaluable. Your veterinarian may ask questions related to colonic and rectal inflammation.

If you can supply a fresh sample of fecal matter, be sure to do so as the veterinary team will want to check for possibilities like bacteria or parasites. Blood tests will be ordered and may reveal the presence of problems like neutrophilia, anemia, hyperglobulinemia, or neutrophilia, all of which have been documented in canines with this condition. In addition, your veterinarian may want to do an ultrasound. This can show tissues changes in the colon and abnormal lymph nodes, two typical findings with colitis and proctitis. Sometimes a rectal examination is done; this will depend on whether it causes pain for your pet, and depending on his cooperation as well. Your veterinarian might discuss the need for a colonoscopy or colon biopsy, both which will require preparation before the tests can be carried out.

If the colitis or proctitis has been caused by parasites, a medicine (anthelmintic) to eliminate the pest will be administered. In infectious cases, antibiotics may be given. With a suspected food intolerance, your dog may be put on a hypoallergenic or bland diet for a few weeks to a few months. Strict compliance to the diet is essential in order to determine if this is the problem. Fiber supplementation may help with the formation of the feces which, in turn, can aid in the improvement of colonic muscle contraction.

If there is inflammation as a result of an inflammatory/immune issue, corticosteroids or motility modifiers could be prescribed, each with it’s own protocol and precautions. In the instance of severe damage to the colon due to chronic inflammation or severe infection, surgery to remove the damaged area and resection the colon could be suggested.

Most dogs with colonic or rectal inflammation respond well to therapy. With the right treatment for the condition, results can be seen within 3 to 5 days. When a hypoallergenic diet is being investigated a diagnosis may take some time to define. Follow-up appointments will be needed so the veterinarian can determine if the therapy is the right choice. The need to monitor the health of your furry family member is necessary as well in case there are reactions to medications. Keep in close contact with the veterinary team and do not hesitate to contact them if you have any concerns.
