Ingestion of Foreign Bodies in Dogs & Cats

Squeaky toys, socks, even corn on the cob can all pose a risk of foreign body obstructions in dogs. While some dogs are able to pass these objects in their stool, other dogs will become obstructed. This causes both damage to the intestines and a life-threatening condition. In the following article, I will discuss G.I foreign bodies and obstructions as well as the clinical signs and treatment.

We all know some dogs are “keen” on getting into things they shouldn’t. There are a lot of both man-made and natural substances that can get stuck in the G.I tract. Some of the more common items in dogs include socks, balls, the centers of squeaky toys, and even corn on the cob. Cats, tend to like to eat strings, yarn, rubber bands and other linear objects like cords from curtains.

In some cases, a dog or cat may be able to pass or defecate the foreign body, in other cases, the object becomes lodged or stuck in the stomach or small intestines, causing a life-threatening condition. This occurs for two reasons. First, damage to the G.I tract can cause adhesion and scarring. If a foreign body causes a perforation, bacteria from the G.I tract will be spread into the abdomen, causing a condition known as sepsis, or a systemic body infection. It is also important to note that some objects may stay in the stomach for several months before shifting positions and getting lodged in a place that causes an obstruction.

Second, a true G.I obstructed patient will be unable to digest food and defecate, or will only be able to defecate the small amount of material that can pass by the obstruction. As a result, a state of malnutrition will occur, causing a patient to be unable to metabolize food and gain the energy needed from it. Over relatively short periods of time, the patient will lose weight and become emaciated.

Dogs and cats with G.I tract obstruction will likely have a history of vomiting, not defecating or only defecating small amounts, and may Lose Appetite eating only the most enticing things or not at all. Over the course of just a week to a few weeks, they can lose a significant amount of weight.

If you think your dog or cat may have eaten something that could cause a G.I obstruction, it is very important to schedule an appointment with your Veterinarian right away. Your veterinarian will obtain a history and it is very important to mention if you think your pet ate something they shouldn’t have, and what that object or thing is. Your veterinarian will then perform a thorough physical examination, and when possible, attempt to feel your pet’s G.I tract from the outside, attempting to palpate for any foreign objects.

If a foreign body is suspected, radiographs are the first diagnostic test often recommended. X-rays can detect foreign objects made of metal or mineral (calcium bones for example) but are not able to see all things a patient could ingest. However, in many cases, x-rays may reveal an “obstructive pattern”, meaning dilated intestines that appear as a result of the obstruction. If radiographs are suspicious but not fully diagnostic, an ultrasound is recommended which is an even more sensitive test.

If a foreign body is diagnosed, surgery will likely be recommended to remove it, especially in cases where it appears unlikely that the obstruction will pass on its own. In these cases, exploratory surgery is recommended to remove the foreign body. With removal, many patients will do well and will return to full function shortly after surgery.

As always, an ounce of prevention is worth a pound of cure. If you think your pet is prone to getting into things they shouldn’t, taking great care to avoid the opportunity for your dog or cat to eat something is of paramount importance. Some things which can help include keeping your laundry in a closed closet and off the floor; keeping pets away from children’s toys and tempting items like hair bands and pencils; taking trash containing food (peach pits, corn on the cob, chicken bones) directly to an outdoor trash can and generally pet-proofing your home.
