Blockage is an emergency: what to do first
If you think your dog has an intestinal or stomach blockage, contact a veterinarian or emergency animal hospital right away. A blockage can be life-threatening, and there is no reliable home treatment.
While you arrange care:
- Phone the clinic and tell them what your dog may have swallowed and when.
- Do not give food, treats, or home remedies unless a vet tells you to.
- Do not give human medicines.
- Do not try to make your dog vomit unless a vet specifically instructs you to. It can be dangerous if the object is sharp or the esophagus is affected.
- Keep your dog calm and limit activity.
- If possible, bring the packaging or a sample of what was swallowed.
What an intestinal blockage is
A blockage, or obstruction, happens when something partly or fully prevents food, fluid, and gas from moving through the stomach or intestines. Blood supply to the bowel can be affected, which is why timing matters.
Signs of a blockage
Signs vary with where the blockage is and whether it is partial. Common ones include:
- Repeated vomiting or retching
- Loss of appetite
- Lethargy or weakness
- Belly pain, bloating, whining, or a hunched posture
- Straining to poop, diarrhea, or small amounts of stool
- Dehydration
Not every dog shows every sign, and some seem only mildly unwell early on. If a swallowed object is possible and your dog is vomiting, do not wait to see if it passes.
Will a dog still poop with a blockage?
Sometimes. A dog with a partial blockage may still pass some stool, even diarrhea, and a complete blockage may produce little or none. Passing stool does not rule out a blockage.
Common causes
Dogs of any age can swallow things they should not. Common culprits include toys or parts of toys, socks and fabric, corn cobs, bones, rawhide pieces, fruit pits, and rocks. Less often, masses or other conditions can narrow the bowel.
What not to do at home
There is no safe way to treat a suspected blockage yourself. Laxatives, oils, bread, or other “tricks” can delay care. Waiting overnight for signs to settle can make the problem worse. Home diarrhea steps such as those in home treatment for dog diarrhea are not appropriate if you suspect an obstruction.
How vets diagnose a blockage
A vet will examine your dog, feel the belly, and ask about what might have been eaten. X-rays are commonly used, and ultrasound or contrast studies may be added. Bloodwork helps assess hydration and organ function. Sometimes objects do not show clearly on X-ray, so the vet may recommend further imaging or monitoring.
Treatment options
The right treatment depends on what the object is, where it sits, and how unwell your dog is. Your vet will decide.
Supportive care and monitoring
For some dogs with a small object or a partial blockage that is clearly moving, vets may use fluids and close monitoring. This should be a vet’s decision, since a blockage can change quickly.
Endoscopy
For certain objects in the stomach, a vet may be able to retrieve the item with an endoscope under anesthesia, avoiding surgery. This is not possible for every object or location.
Surgery
Many blockages need surgery to remove the object. If part of the bowel is damaged, that section may need to be removed. Your dog will usually need anesthesia, pain control, and hospital care afterward.
Can a dog survive a blockage without surgery?
Some objects do pass on their own, but it is not possible to know at home which ones. Untreated blockages can cause serious illness or death. Veterinary assessment is the only way to decide whether surgery is needed.
How long can a blockage last?
There is no reliable timeline. Signs can develop within hours or days, and the risk generally rises the longer an obstruction is present. Because this varies, any suspected blockage should be treated as urgent.
How much does treatment cost?
Costs vary widely depending on your region, the clinic, the tests, whether surgery is needed, and the length of hospital stay. Ask the clinic for an estimate before treatment, and ask about payment options if you are concerned. Pet insurance may help if you already have a policy, so check what it covers.

Recovery
After treatment, vets usually give instructions on rest, feeding, medications, and wound care if surgery was performed. Meals often restart gradually with small, gentle portions. Your dog may need a protective cone and restricted activity. Follow your vet’s plan, and call if you notice vomiting, a drop in appetite, a swollen or painful belly, or changes to the incision.
Preventing blockages
- Choose toys sized appropriately for your dog, and replace worn ones.
- Keep socks, underwear, string, and small objects out of reach.
- Secure garbage and watch your dog around corn cobs and cooked bones.
- Supervise chewing, and take away items that are breaking apart.
- Ask your vet about dogs who frequently eat non-food items.
Frequently asked questions
Is yellow vomit a sign of a blockage?
It can be, but yellow bile vomiting also happens with an empty stomach. Repeated vomiting, a painful belly, or a possible swallowed object make a blockage more likely. See dog vomiting yellow for more.
Should I treat blockage-like diarrhea at home?
Not if you suspect an obstruction. Read when to see a vet for dog diarrhea for the red flags that should lead to a vet visit.
