Why do dogs with intussusception bleed?

Dogs with intussusception bleed because their intestines are damaged, which is the main pathological feature of the disease. Dogs suffering from intussusception mainly present with loss of appetite, intractable vomiting, mucus and bloody stools, tenesmus, etc. In the early stages of intussusception in dogs, it can be corrected by palpating the abdominal wall. If it doesn't work, a caesarean section should be performed as soon as possible. If intussusception lasts too long, adhesion will occur in the intestinal wall and cause necrosis.
