Intussusception in Dogs: Causes, Symptoms & Treatment

Intussusception in dogs is a critical medical emergency where part of the intestine folds into a neighboring section, leading to a dangerous blockage. Though most often seen in the small intestine, sometimes the large intestine can be involved. This condition interrupts digestion and demands immediate care from a veterinarian to avoid life-threatening complications.

Certain breeds tend to have increased susceptibility, including Pug puppies, Puggle puppies (a Pug and Beagle mix), and Jug puppies (a Jack Russell and Pug hybrid). However, intussusception can affect dogs regardless of breed or age, so it’s essential for all pet parents to recognize this condition.

What is Intussusception in Dogs?

The dog’s intestine is a long, flexible tube responsible for absorbing nutrients during digestion. With intussusception, one part of the intestinal tract slides inside another, similar to how a collapsible telescope works. This causes decreased blood flow to the affected area, swelling, and can result in tissue death if treatment is delayed. Because the condition can worsen quickly, spotting the signs early is vital for your dog’s survival.

Main Causes and Risk Factors

Intussusception typically occurs due to disrupted or abnormal bowel movements from various health issues. Common causes include:

• Parasite infections causing abnormal intestinal motility
• Bacterial or viral gastrointestinal infections, such as canine parvovirus or bacterial gastroenteritis
• Ingesting foreign objects, including plastic pieces or small toys, that obstruct the intestine
• Inflammatory bowel diseases hampering gut function
• In some cases, the exact cause remains unknown

Puppies, particularly those around three months old, are most at risk, although adult dogs can develop intussusception too. German Shepherds appear to have a higher likelihood, but vigilance is important for any breed.

Signs and Symptoms to Watch For

Symptoms often resemble other digestive problems but are more severe and require urgent attention. Look for:

• Ongoing vomiting caused by intestinal blockage
• Diarrhea, which may include mucus resembling jelly
• Refusal to eat or decreased appetite
• Swelling or tenderness in the belly area, noticed when gently pressing the abdomen
• General weakness or discomfort
• Reduced or completely halted stool production following normal bowel movements past the blockage

How Intussusception is Diagnosed

If you suspect intussusception, take your dog to the veterinarian immediately. The evaluation will likely involve:

1. A physical exam to feel for unusual lumps or painful areas in the abdomen
2. Fecal tests to eliminate parasitic causes
3. Bloodwork to assess hydration levels and electrolyte balance
4. Imaging tests such as abdominal X-rays with barium contrast or an ultrasound to pinpoint the obstruction and confirm intestines have telescoped
5. Exploratory surgery may be required if these tests are inconclusive

Treatment Options: Surgery and Aftercare

This condition will not resolve on its own and demands surgical repair. Surgical treatments may include:

• Manual reduction, which involves sliding the folded intestine back into place if no necrosis has occurred
• Removal of damaged sections followed by reconnecting (intestinal resection and anastomosis)
• Enteroplication, tacking intestinal loops together, to reduce recurrence risk especially in dogs with previous episodes

After surgery, your dog will generally require a hospital stay for several days to recover and receive supportive care. Quick intervention and attentive post-operative care increase the chances of full recovery.

Preventative Care and Ethical Dog Ownership

While not all cases of intussusception are preventable, several steps can help reduce risk. These include maintaining regular worming schedules, providing safe chew toys to discourage swallowing non-food items, and promptly treating infections. Responsible dog owners should also monitor their dog’s gut health and seek veterinary advice at the first signs of digestive upset.

In Summary

Intussusception is a severe, potentially life-threatening condition that is manageable with early diagnosis and treatment. Understanding the causes, symptoms, and surgical options equips dog owners to act decisively. If you have a young pup or belong to a breed with a higher risk, closely observe any changes in appetite, bathroom habits, or overall wellbeing. Don’t hesitate to consult your veterinarian or reputable breeders for guidance and support.
