Signs of Intestinal Blockages in Dogs

If your dog has a habit of swallowing things they shouldn't, then intestinal blockages are a real health concern! Blockages can result in devastating health issues and in some cases, major surgery is required to save your dog's life. Our Oak Grove vets explain more...

What causes intestinal blockages in dogs?

A common cause for concern in all dogs is bowel obstruction, which is when his stomach or intestines have been partially or completely blocked. Blockages cause a number of complications, including preventing food and water from passing through his GI tract and decreasing their blood flow. Your dog can even die from an intestinal blockage within 3-7 days.

Blockages can occur anywhere along the digestive tract. Some may be able to pass into the esophagus, but not into the stomach. Others may pass into the stomach but not into the intestines or become lodged in the intricate twists and turns of a dog’s intestines. 

The most frequent kinds of bowel obstructions are foreign bodies. Every pup runs the risk of swallowing 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, other common bowel obstructions to look out for are masses or tumors. 

How do I know if my dog has an intestinal blockage?

The symptoms of intestinal blockages in dogs are similar to symptoms of a gastrointestinal illness and include: 

  • Constipation or straining to poop
  • Vomiting
  • Loss of appetite
  • Weakness
  • Nausea
  • Diarrhea
  • Painful abdomen to the touch
  • Whining
  • Bloating
  • Dehydration
  • Restlessness
  • Aggressive behavior when the abdomen is touched

If you think (or know) that your dog has ingested something they shouldn't have - or if they are exhibiting the symptoms listed above - call your vet right away, or visit the nearest after-hours animal emergency hospital.

How do vets diagnose dog intestinal blockages?

If you saw your dog eat a foreign object, you might be wondering how you can help your dog pass the obstruction, but you should not attempt this on your own, your dog needs veterinary care.

Your 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.

From there, your dog will be taken to the in-house diagnostic lab for X-rays and any other imaging technique required to try to see the foreign object. One such test is an endoscopy, a procedure that inserts a small tube with a tiny attached camera through your dog’s throat and into the stomach. Your dog would be sedated for this procedure.

What is the treatment for intestinal blockage in dogs?

Treatment for intestinal obstructions can be surgical or non-surgical. Many factors go into this decision including the location, how long the object has been stuck, 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. However, when it comes to a timeline for intestinal blockage in dogs, time is absolutely of the essence. If the object does not pass on its own and your dog has the symptoms listed above, your dog will need to be treated as soon as possible.

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

How is intestinal blockage surgery performed on dogs?

Dog intestinal blockage surgery is a major procedure, requiring your dog to be anesthetized. After the surgery, your dog will stay at the hospital and recover for several days.

For the intestinal surgery, your vet will make an incision into your dog’s abdomen near the blockage site and carefully extract the object. The length of surgery can vary because they may 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 veterinary surgery. Of course, the sooner the surgery is performed, the better.

What should I expect from my dog's recovery after intestinal blockage surgery?

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 surgery and hospitalization, 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, make sure 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 nauseated after surgery and it’s actually common for dogs to vomit afterward. So, your vet may also prescribe medications to relieve your dog’s nausea and vomiting, if needed.

What is the cost of dog intestinal blockage surgery?

The cost of intestinal blockage surgery for dogs can vary dramatically depending on how extensive the surgery is, how long the obstruction has been present, and the length of the hospital stay, as well as your dog's size, age, overall health and where you live.

The only way to get an accurate estimate of your dog's intestinal blockage surgery cost is to ask your veterinary clinic for an estimate. Most animal hospitals are happy to provide clients with a detailed breakdown of costs involved in any procedure. Your veterinary team will also take the time to answer your questions and explain any items on the estimate to you.

How can I prevent my dog from developing an intestinal blockage?

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. 
  • Keep your dogs from scavenging through garbage and debris (outside and inside the house).
