Intestinal Blockages In Dogs: Causes And Treatment

Intestinal Blockages In Dogs: Causes And Treatment

If your dog seems to chew on and eat just about everything in sight, you could be concerned about intestinal blockages. Our Long Island vets see this serious condition often, and if not treated quickly it can cause devastating health issues including needing major surgery to save your dog's life.

Occurrence Of Intestinal Blockages In Dogs

Bowel obstruction is a huge cause for concern in all dogs, and it occurs when a dog's stomach or intestines have been either partially or completely blocked. Blockages cause a number of complications, including preventing food and water from passing through the dog's GI tract and decreasing blood flow. Your dog can even suffer fatal consequences from an intestinal blockage within 3–7 days.

Blockages can occur anywhere in the digestive tract. Some may be able to pass into the esophagus, but not into the stomach, while other obstructions could pass into the stomach but not the intestines. They can also become lodged in the intricate twists and turns of a dog’s intestines.

The most frequent kinds of bowel obstructions are foreign bodies. Dogs are curious and they run the risk of consuming some surprising items: toys, trash, socks, underwear, dish towels… the list goes on! String, yarn, and rope fibers are especially hazardous for dogs because they can cause intestinal twisting. With older dogs, some additional bowel obstructions to watch for are masses or tumors.

Signs Of Intestinal Blockages In Dogs 

Unfortunately, unless you witnessed your dog swallow a foreign object, the symptoms of intestinal blockage could be misunderstood as merely an upset stomach. Here are some signs that your dog might have an intestinal blockage:

  • Vomiting
  • Loss of appetite
  • Weakness
  • Nausea
  • Diarrhea
  • Straining or unable to defecate
  • Exhibits pain when the abdomen is touched
  • Whining
  • Bloating
  • Dehydration
  • Restlessness
  • Aggressive behavior when the abdomen is touched

If you think your dog ingested something suspicious or they are exhibiting the symptoms listed below, call your veterinarian as soon as possible.

Diagnosis for intestinal blockages in dogs

If you saw your dog eat a foreign object, you might be wondering how you can help your dog pass the obstruction. Note that you should not attempt this on your own, because your dog needs veterinary care for the best chance at recovery.

Your primary vet will first perform a physical exam on your dog, paying special attention to the abdomen. They may also perform blood work to determine if the blockage is affecting your dog’s overall health.

Treatment for intestinal blockages in dogs

Treatment for intestinal obstructions can be either surgical or non-surgical. There are many factors that go into making this decision including the location of the blockage, how long the obstruction has been there, and the size, shape, and structure of the object.

In some cases, a vet can retrieve the foreign object with an endoscope. If this is not possible, your vet likely will consult the ultrasound or X-Rays to determine where (and what) the obstruction is.

Some foreign objects, given time, can pass on their own. When it comes to intestinal blockage in dogs, however, there is no time to waste. If the object does not pass on its own and your dog has the symptoms listed above, they need to be seen by a veterinarian as soon as possible.

If your vet determines that the foreign object presents an immediate danger, emergency surgery is ordered.

Surgery For Intestinal Blockage For Dogs

Dog intestinal blockage surgery is a major operation that necessitates your dog being anesthetized. After the surgery, your dog needs to recover at the animal hospital for several days.

During the intestinal surgery, your vet will make an incision into your dog’s abdomen near the blockage site and carefully extract the object. The duration of the surgery could vary because of the need to repair any damage to the stomach or intestinal wall resulting from the obstruction.

Your dog’s survival after surgery to remove an intestinal blockage depends on a few things:

  • Size, shape, and location of the foreign object
  • How long the foreign object has been stuck in the intestines
  • Your dog’s health before the surgery

The physical exam and diagnostic tests that your vet performs before surgery will help them determine how well they think your dog will do after surgery. Of course, the sooner the surgery is performed, the better.

Post-Surgery Recovery

The most critical period for your dog is the first 72 hours after surgery. If the patient is doing well after 72 hours then they typically recover well, but there are still some potential complications:

  • Sepsis (blood poisoning)
  • Hypoalbuminemia (low protein count)
  • Dehiscence (Wound separation or opening)

After your dog's procedure, monitor your dog and keep their activity level very low. Stick to short walks for at least a week — you don’t want their sutures to tear. Your dog will also need to wear a cone to keep them from chewing on the healing incision.

It’s important to feed your dog small amounts of bland food before gradually transitioning to his previous diet during this time. Also ensure they are getting enough fluids to prevent dehydration.

Major surgery is painful. Your dog won’t be in pain during the surgery, of course, but will probably feel some pain afterward. Your vet will prescribe post-surgery pain medication for your dog. Follow the prescription instructions carefully to keep your dog’s pain under control at home and fight off infections.

Anesthesia can make some dogs feel ill after surgery, making it common for dogs to vomit afterward. So, your vet may also prescribe medications to relieve your dog’s nausea and vomiting, if needed.


The best way to prevent intestinal blockages in your dog is to limit their chances of ingesting non-food material.

  • Putting things your dog may eat out of his reach.
  • Be vigilant about items in the house and track when they are missing.
  • Keep an eye on your dog while he is playing with his toys or chewing on rawhide or bones.
  • Prevent your dogs from scavenging through garbage and debris (outside and inside the house).
