Intestinal Blockage in Dogs: Signs and Emergency Care
Dogs explore the world with their mouths, and some swallow things that cannot get through. A blockage can become life-threatening within days.
What happens
An object lodges in the stomach or intestine and stops food and fluid from passing. The gut above it stretches, blood supply can be reduced and the wall may be damaged or rupture. Linear objects such as string or ribbon can bunch up the intestine and cut into it.
Common culprits
- Socks, underwear and fabric
- Toy pieces, balls and rawhide fragments
- Corn cobs, fruit pits and bones
- Stones, sticks and hair ties
- String, thread and tinsel
See safe dog chews guide and how to choose safe dog toys.
Warning signs
- Repeated vomiting, often after eating or drinking
- Loss of appetite
- Abdominal pain or a tense belly
- Lethargy or hiding
- Straining, diarrhea or no stool
- Dehydration
If you saw your dog swallow something, call your vet or an emergency clinic even before signs appear. See dog emergency warning signs.
What to do
- Call your vet or emergency clinic and describe the item, size and timing.
- Do not induce vomiting unless told to. Sharp objects, some materials and certain situations make it dangerous.
- Bring packaging or a similar item to help them judge size and material.
- Withhold food until you have been advised.
How vets diagnose it
Your vet will examine your dog and may recommend X-rays, ultrasound or contrast studies. Not all objects show on X-rays, so imaging may be repeated or combined with other tests.
Treatment
Options depend on the object and location:
- Induced vomiting in selected recent cases under veterinary supervision
- Endoscopy to retrieve objects in the stomach or upper gut
- Surgery to remove objects lodged in the intestine, sometimes with removal of damaged bowel
- Fluids, pain relief and anti-nausea medication around the procedure
Recovery depends on how long the object was in place and the condition of the bowel.
Prevention
- Keep laundry, trash and small objects out of reach
- Choose toys sized appropriately for your dog and replace damaged ones
- Supervise chewing and avoid cooked bones
- Teach "drop it". See how to teach drop it
- Manage scavenging on walks. See how to stop a dog eating things on walks
Common mistakes
- Waiting to see if it passes
- Inducing vomiting at home without advice
- Giving laxatives or oil
- Ignoring repeat vomiting
Troubleshooting
- My dog swallowed a sock but seems fine: call anyway, since early treatment is easier.
- My dog vomits after every meal: seek an exam.
- My dog keeps eating socks: talk to your vet and a trainer about management and boredom.
A simple plan
- Dog-proof the house.
- Pick safe, correctly sized toys.
- Train a reliable drop it.
- Call your vet quickly if something is swallowed.
Real-life examples
A lab eats a sock and has it removed by endoscopy the same day. A terrier vomits for two days before a corn cob is found and surgery is needed. A puppy swallows a hair tie and passes it after close monitoring. Speed of action matters.
Staying one step ahead
Look at your home from a dog's level. Anything small, soft or smelly is a candidate for swallowing.
Why some dogs are repeat offenders
Some dogs, often young retrievers, terriers and puppies, swallow non-food items repeatedly. Boredom, under-exercise, anxiety and attention seeking can all play a part, and in some dogs the habit, called pica, has a medical link. If your dog has swallowed items more than once, mention it to your vet and consider extra enrichment, puzzle feeders and structured exercise.
What recovery looks like
After surgery or endoscopy, dogs are usually kept on a gentle diet, restricted activity and medication for several days. Your vet will explain wound care, signs of complications and when to recheck. Keep the cone on if advised, and call promptly if vomiting returns, the belly looks swollen or your dog stops eating again.
The takeaway
Blockages are emergencies. Call early, avoid home remedies and prevent access to risky items.
