Help pay for Cooper's surgery

Cooper is a 13 week old lab mix puppy that has a rare condition called Intussusception. Intussusception (pronounced in-tuh-sus-sep-shun) describes a condition in which one segment of the intestine (the intussusceptum) telescopes or invaginates into the lumen of an adjacent segment of intestine (the intussuscipiens). Intussusceptions may occur at any location in the gastrointestinal tract from the stomach to the large intestine. However, most commonly, the bowel segments involved are the middle of the small intestine (jejunum ) or the where the small intestine joins the large intestine or colon (ileocecocolic junction). Generally the intussusceptum is a more proximal portion of bowel (i.e., closer to the mouth) which telescopes into a more distal (i.e., closer to the anus) segment. This pattern follows the normal direction of peristalsis. The reverse, however, is occasionally found. Intussusceptions are most commonly associated with some problem that causes inflammation of the intestine (enteritis). Common causes of enteritis are: intestinal parasites (hookworms, whipworms, and roundworms) protozoal, bacterial or viral infections (Giardia, Salmonella, canine distemper, and parvovirus) intestinal foreign bodies (bones, plastic toys, etc.) abrupt dietary changes intestinal masses (tumors) a surgical procedure performed on the intestine Increased motility in a segment of intestine (hypermotility) which is adjacent to a segment that has lack of motility (ileus) can cause the hypermotile segment to telescope into the segment with ileus, resulting in an intussusception.
