Megaesophagus

Megaesophagus is a disease of the esophagus characterized by low motility and dilation. Most cases in adult dogs are idiopathic. It is the most common cause of regurgitation in dogs. Other causes of megaesophagus include myasthenia gravis, lead poisoning, and Addison's disease.

Normally, when the dog's esophagus is functioning properly, it acts as a muscle and pushes the food down the esophagus into the stomach. However, when a dog has megaesophagus, the esophagus stays enlarged and does not push the food down to the stomach. Therefore, the food fails to enter the stomach and often stays in the esophagus, and is eventually regurgitated, or enters the lungs through breathing, or decays in the esophagus.

One of the primary dangers to a dog with megaesophagus is aspiration pneumonia. Because the food stays lodged in the throat, it can often be inhaled into the lungs causing aspiration pneumonia. One way to avoid this is to make sure that every time the dog eats or drinks anything, that the dog sits for at least 10 minutes afterwards or is held in a sitting up or begging position. This requires that all food and liquid intake be closely monitored and specifically administered to the dog in regular intervals (sometimes as often as 2-3 hours) in smaller quantities. Obviously, if smaller quantities of food and water are administered, one needs to take the necessary precaution to ensure the dog has a sufficient caloric and water intake. The prognosis for this condition is guarded.

Breeds affected:

German Shepherd Dog
Golden Retriever
Great Dane
Greyhound
Irish Setter
Labrador Retriever
Miniature Schnauzer
Persian (cat)
Purebred Shih tzu
Shar Pei
Siamese (cat)

Aspiration pneumonia is bronchopneumonia that develops due to the entrance of foreign materials that enter the bronchial tree, usually oral or gastric contents (including food, saliva, or nasal secretions). Depending on the acidity of the aspirate, a chemical pneumonitis can develop, and bacterial pathogens (particularly anaerobic bacteria) may add to the inflammation.
