Gastrointestinal Foreign Body in Dogs

Overview of Canine Gastrointestinal Foreign Bodies

Gastric or gastrointestinal foreign bodies is a term that refers to any material other than food that is eaten by a dog and results in a serious digestive problem in the stomach. They are often referred to simply as “foreign bodies”. Gastric means the foreign material is in the stomach and gastrointestinal (GI) means it is in the stomach and/or intestine. Foreign bodies such as toys, string, clothing and plastic can become lodged and create an obstruction. Any household object your dog chews on can become a foreign body problem.

Dogs of any age are susceptible to developing foreign body problems but this is most commonly seen in young dogs less than 2 years of age. These youngsters are naturally curious and enjoy chewing.

Although some smaller foreign bodies can pass through the gut without getting stuck, the larger pieces can result in serious gastrointestinal complications.

What to Watch For

Diagnosis of Gastrointestinal Foreign Body in Dogs

A complete and thorough medical history is important in diagnosing a gastric foreign body, including recent exposure or known chewing on foreign material. Physical exam findings can help your veterinarian determine the appropriate diagnostic tests. Test recommendations may include:

Treatment of Gastrointestinal Foreign Body in Dogs

Most dogs with a gastric foreign body obstruction have been vomiting or not eating for a period of time. This leads to dehydration and electrolyte imbalance. Your veterinarian will recommend hospitalization with intravenous fluids prior to anesthesia.

Once your dog is more stable, he will be anesthetized and the foreign object will be removed by one of two primary methods: endoscopy or surgery.

After sedation, your dog will have his mid abdomen shaved. An incision is made along the center of the abdomen. The stomach and intestines are examined for foreign material or obstructions. After localizing the foreign material, a small incision is made in the stomach or intestine and the foreign material is removed. The incision in the stomach or intestine is sutured. The body wall and skin is then sutured.

Advantages of surgical removal of foreign material is the ability to examine the entire intestinal tract for other obstructions. Disadvantages include post-operative pain, prolonged hospital stay and potential for infection from the stomach or intestinal incision.

After removal of the foreign material, the dog is continued on intravenous fluids until vomiting has stopped and he is able to eat and drink without vomiting. Post-operative pain medication such as butorphanol as well as antibiotics may be given.

Based on the severity of intestinal damage, your dog may require 2-5 days of hospitalization.

Home Care of Dogs with Gastrointestinal Foreign Bodies

Once the dog is able to eat and drink without vomiting, he is sent home.

For those dogs treated with endoscopy, there is minimal at home care. Feed a bland diet for two to three days and gradually return to a normal diet. Watch for not eating or vomiting.

For those dogs undergoing surgery, at home care includes incision care. Do not allow your dog to lick or chew at the sutures. An Elizabethan collar may be needed. Watch the incision for swelling or discharge. Sutures are generally removed in 7-10 days. Feed a bland diet for two to three days and gradually return to a normal diet. Watch for not eating or vomiting.

Preventative Care

The best way to prevent gastric foreign bodies is to prevent access to objects that could be swallowed. Allow your dog to only chew on toys that cannot be swallowed.

If you suspect that your dog may have ingested something that may not pass through his intestinal tract, contact your veterinarian. Waiting until your dog starts to vomit will make removal of the foreign material more difficult and costly.
