Dog Esophagus Problems

Your dog's esophagus lives pretty much in the shadow most of the time, until it gives signs of trouble. At that point we become aware of its presence, and the way it affects the dog when a foreign body interferes with its proper functioning. The esophagus is a muscular tube that connects the dog's mouth with the stomach. Its name derives from the Greek word "oesophagus" meaning "entrance for eating." Food will be chewed up in the mouth, then will be swallowed through the pharynx, (where the epiglottis will fold down to prevent entrance into the trachea) and then the bolus will go down the esophagus passing near the heart through the diaphragm muscle and right up into the the stomach. All this process takes is about five seconds, a very small lapse of time that often leaves owners with little time to intervene in the case the dog swallows a foreign object!

Normally, the esophagus expands quite a lot to allow the food to pass through, but when a foreign object is swallowed, it may get lodged in the esophagus whether because of size or having sharp points. The majority of obstructions occur lower in the neck area at the thoracic inlet, but they can also occur by the pharynx, base of the heart or by the level of the diaphragm. Typically, balls, rocks, sticks, triangular bones such as pork chops and fishhooks tend to lodge in this area. Small breed dogs are particularly prone to esophageal obstructions. In the following paragraphs we will see symptoms of esophagus blockages and treatment options.

Signs and Treatment of Esophageal Blockage in Dogs

When a dog's esophagus is blocked, most dog owners will become aware of the problem as the symptoms are quite noticeable. Yet, treatment may be delayed because owners may not understand what exactly has happened especially if they haven't witnessed the dog swallowing any foreign object. Consider that semi-solid food and water may be still able to pass past the blockage if it is partial.The following are symptoms suggesting an esophageal obstruction in dogs.

Veterinarians who suspect an esophageal blockage must take neck and thoracic radio graphs. Recognizing a blockage may be tricky at times, as plain x-rays may reveal only ill-defined soft tissue opacities. Endoscopy (the insertion of a tube with a camera on end) is the ideal method to remove the blockage with the pet under anesthesia, and when this is unsuccessful, surgery is usually the next step. If the esophagus is found to be damaged from the foreign object, a course of antibiotics and anti-inflammatories will be prescribed. If erosions were present on the lining of the esophagus, restriction of food or water may be necessary for a few days so to allow the esophagus to heal. Allowing a dog with an esophageal blockage to drink or eat may cause aspiration into the lungs; better off seeking the vet immediately.

Failure to treat an esophageal blockage in a timely manner may lead to severe complications such as esophageal stricture, esophagitis, subcutaneous emphysema, perforation, pneumothorax, aspiration pneumonia, and transient megaesophagus.

Prevention is the best course of action for preventing esophageal obstructions in dogs. Keep away from your dog small items that can be swallowed. Dogs have been known to ingest the oddest things including panty hose, underwear, socks, hair ties and corn cobs. It's always a good idea to keep such items out of reach and train the drop it and leave it command as back-ups. Bones though seem to be the prevalent cause for these types of blockages, according to the Merck Manual. Also, according to a 2007 review conducted by veterinarians at The AMC and published in the Journal of Veterinary Emergency and Critical Care, 60 dogs with foreign bodies stuck in the esophagus were evaluated. Out of the 60, 46 of them had bones lodged, whereas 14 had various toys, food objects and plastic lodged in their esophagus.

Thanks, we had a small dog once show up at the vet with a blockage caused by a Greenie and the vet used the endoscope, split it in pieces and sent some down the stomach and collected the bigger piece.

It's amazing that we don't see more of this in dogs, considering what they eat when we're not looking. Great article and great advice. Voted up!

Eman, I hope not, hopefully your vet will be able to pinpoint the problem and determine if it's related to the esophagus or not.

My blue healer mix ate a rib bone a few weeks ago, and now, on occasion only, makes noises like he's trying to clear his throat. It in no way keeps him from eating, exercising, or really anything except that he's obviously trying to clear something. He drinks fine. He's highly energetic, and sometimes he doesn't make that noise at all, and I think it has passed. Is there anything he can swallow that might dissolve, or help to pass a small obstruction?
