Clinically found mainly in the anterior segment of the intestine into the posterior segment of the intestine to jejunum, ileum sets the colon the most common. Dog intestine intussusception is more common in clinical, mainly caused by cold, enteritis, parasitic infections caused by intestinal motility disorders, and easily secondary to canine parvovirus disease and other diseases. Clinically easy and intestinal constipation, intestinal obstruction, intestinal foreign body, spleen and other symptoms of abdominal pain were confused with the disease, mainly through imaging and open surgery for diagnosis ~ ([1]). Now through a case of dogs with severe intussusception cases to explore the diagnosis and disease
