How to Tell If Your Dog Has a Blocked Intestine
A blocked intestine, or intestinal obstruction, can be a life-threatening emergency for dogs. Understanding how to recognize the signs can help save your pet’s life. This condition occurs when a partial or complete blockage prevents the normal passage of food, fluids, and gas through the gastrointestinal (GI) tract. It's most commonly caused by the ingestion of foreign objects but can also result from tumors, hernias, or complications after surgery. Here’s what every dog owner should know.
Common Causes of Intestinal Blockage
- Foreign Bodies: Dogs often swallow inedible objects such as socks, toys, bones, rocks, or tampons. Linear items like string or yarn are especially dangerous.
- Tumors: Especially in older dogs, growths along the intestines can cause blockages.
- Intussusception: A piece of the intestine telescopes into another section, causing an obstruction.
- Hernias: Portions of the intestines protrude and become trapped in abnormal locations.
- Previous surgeries: Scar tissue or adhesions can lead to narrowing or blockage.
- Severe parasite load: Worms can accumulate and hinder passage.
Breeds and Dogs at Higher Risk
Younger, large-breed dogs—especially Labrador Retrievers, Golden Retrievers, and Bernese Mountain Dogs—are prone to swallowing objects. However, any breed or age can be affected.
Signs and Symptoms
Obstruction symptoms vary depending on the location and extent of the blockage. Some signs to watch for include:
- Vomiting: Often frequent, may contain blood or fecal matter, or may be unproductive.
- Diarrhea or Constipation: Some dogs may have diarrhea, others may struggle to pass stool entirely.
- Abdominal pain: Dogs may whine, be restless, have a bloated or tender abdomen, or resist touch.
- Loss of Appetite: Anorexia is common, with dogs refusing to eat.
- Lethargy and Weakness: Dogs become withdrawn and lose energy quickly.
- Posture changes: Some dogs assume a "prayer position" with their front legs stretched forward and back legs elevated.
- Gagging or Heaving: Especially after eating or drinking.
- Drooling or Burping: Signs of gastrointestinal upset and possible blockage.
- Dehydration: Often due to vomiting or inability to retain fluids.
- Weight Loss: In chronic or partial blockages.
Diagnostic Methods
If you suspect a blockage, visit a veterinarian immediately. Diagnostic steps may include:
- Physical examination: The vet will palpate the abdomen to detect pain or swelling.
- Imaging: X-rays and ultrasound are commonly used to locate the obstruction.
- Contrast studies: A dye is ingested to improve imaging accuracy.
- Endoscopy: Using a camera-equipped tube inserted orally to examine or retrieve objects.
- Blood work: Evaluates dehydration, infection, or electrolyte imbalances.
Treatment Options
The method of treatment depends on the object size, material, location, and dog's condition:
- Conservative monitoring: In rare cases, small, smooth objects may pass under supervision.
- Endoscopic removal: If the obstruction is accessible and facilities are equipped, endoscopy may be used.
- Surgery: Most cases require surgical removal, especially if the dog is seriously ill or imaging shows a complete blockage. The dog is stabilized with IV fluids before surgery.
During surgery, the veterinarian removes the object and repairs any affected tissues. If there’s tissue necrosis or perforation, sections of intestine may be removed.
Post-Surgical Care and Monitoring
- Close observation: First 72 hours post-op are critical for complications like infection or suture failure.
- Restricted activity: Rest is needed to ensure proper healing.
- Medication: Painkillers, anti-nausea drugs, and antibiotics may be prescribed.
- Diet: Start with bland foods and reintroduce regular food gradually.
- E-collar: Prevents the dog from licking or biting the incision area.
Prognosis and Outcome
Recovery depends on how quickly the condition is diagnosed and treated. If addressed early, most dogs recover well. However, if there has been prolonged blockage, tissue damage, or peritonitis, the prognosis becomes guarded.
How to Prevent Intestinal Blockages
- Secure household items: Keep small or chewable objects out of reach.
- Monitor playtime: Choose durable toys too large to be swallowed.
- Restrict access: Prevent scavenging from garbage or outdoor debris.
- Regular checks: Ensure no socks, strings, or other tempting objects are missing.
- Address behavioral issues: Dogs with pica or high curiosity should be trained or managed accordingly.
When to See a Vet
If your dog shows any of the symptoms mentioned above, or if you suspect they've ingested a hazardous item, consult a veterinarian immediately. Early intervention drastically improves outcomes. Delaying treatment, even by a day or two, can increase risks of complications or death.
