Inflammation of the Colon or Rectum in Dogs
Colitis and Proctitis
Both dogs and cats suffer from a certain kind of bowel disease called histiocytic ulcerative colitis. This disease causes the lining of the animal’s colon to thicken, with varying degress of loss to the superficial lining (known as ulceration). The thickening is due to the infiltration of various cells in the layers under the lining. And when the colon becomes inflamed, there is a reduction in the colon’s ability to absorb water and store feces, leading to frequent diarrhea, often with mucus and/or blood. Proctitis, conversely, is the inflammation of the animal’s anus and the lining of the rectum.
