What is an intestinal intussusception in dogs?

Intussusception is when one part of the intestine goes inside another part of the intestine. This can happen when the intestine gets a fold in it, and the fold pinches off a small piece of the intestine. This can block the intestine and cause severe gastrointestinal symptoms. The small intestine, large intestine, and multiple locations can all be involved. More than two-thirds of cases in dogs and cats are caused by intussusception in the small bowel (ileum portion) to the large bowel.
