Veterinary Guide to Intussusception in Dogs (2025)🐶

By Dr. Duncan Houston BVSc

🔍 What Is It?

Intussusception occurs when one section of the intestine telescopes into an adjacent segment, creating a blockage that can cut blood flow and cause necrosis. It's most common in puppies under 1 year, though it can occur in older dogs. 🩺

💡 Common Causes & Risk Factors

Often idiopathic but may follow gastrointestinal inflammation—enteritis, parasites, surgery, foreign bodies, cecal inversion, or tumors.
Puppies (<12 mo) are especially at risk, but any age can be affected.

🚨 Signs to Watch For

Sudden vomiting, diarrhea (possibly bloody), decreased appetite, lethargy, and dehydration.
Abdominal pain—dogs often hunch (“praying position”), cry, or whimper; may have palpable tubular abdominal mass.
Signs may wax and wane if partial—intermittent episodes for weeks are reported in some cases.

🔬 Making the Diagnosis

Physical exam may reveal pain or an abdominal “sausage” mass.
X-rays: look for signs of bowel obstruction—fluid/gas-distended loops.
Ultrasound: most reliable. Concentric “bullseye” (transverse) or “sandwich/pseudokidney” (longitudinal) patterns are diagnostic.
Contrast radiography (barium) is an alternative when ultrasound isn't available.
Bloodwork and hydration status help stabilize pre-surgery.

🛠 Treatment Steps

Immediate care: Hospitalize, aggressive IV fluids, correct electrolytes, pain relief, antibiotics if perforation suspected.
Surgical repair: Laparotomy to manually reduce if viable, or resect and anastomose damaged segments.
Enteroplication: Suturing adjacent loops may reduce recurrence risk (~6–27%)—used selectively due to potential complications.
Special cases: Gastric/esophageal intussusceptions require tailored surgery (e.g., gastropexy, partial gastrectomy).

📈 Prognosis & Follow-Up

Prognosis is good with early surgery and stabilization.
Recurrence occurs in 11–27%, especially without enteroplication.
Post-op care includes gradual reintroduction of food, pain management, hydration, and monitoring for infections or leakage.
Deworming, biopsy, or dietary adjustments may address underlying triggers.

🛡 Prevention & Owner Advice

Maintain parasite prevention and cautious dietary changes.
Prevent foreign body ingestion—secure toys, bones, and household items.
Seek immediate veterinary attention for any GI symptoms—earlier is safer!
