What ‘Flipped Intestine’ (Intussusception) Means in Dogs
📝 Summary
Among dog keepers you often hear 'flipped intestine disease.' It mostly hits puppies — deep depression, frequent vomiting, tarry mucus stool, arched back, constant moaning, high death rate.
1 Overview
Dog owners fear this disease — it’s actually intussusception: one intestinal segment telescopes into another. Poor circulation causes necrosis and blockage; contents ferment and release toxins absorbed by the body.
The direct cause is disordered intestinal motility: one segment over-expands while another strongly contracts, so the contracted segment telescopes in. Many factors disrupt motility.
Some pathogens (viruses, bacteria) disrupt motility. Canine parvovirus and coronavirus often cause fatal intussusception later. Parasites (roundworms, whipworms) secrete toxins. Some drugs cause abnormal motion.
Also, other diseases, fasting, cold, feed changes can trigger it. Diagnose by symptoms: vomiting, arched back and pulled-in belly, moaning pain, tarry mucus stool.
If the telescoped segment is short and recent, massage it out through the abdominal wall; or, if front-to-back, use an enema with 0.1% potassium permanganate (1000–3000 mL by size), repeat. Also give gut-smooth-muscle relaxants like atropine or belladonna to ease spasms.
Most dogs are diagnosed late, with adhered/edematous/necrotic mucosa — operate promptly, with fluids, heart support, and electrolyte correction.
