Description: A hereditary abnormality that causes decreased movement and muscular contractions of the esophagus thus interfering in the normal peristaltic movement that will propel the food from the esophagus to the stomach. Since most of the ingested food remains in the esophagus, a dog with Megaesophagus is often observed to regurgitate food, has bad breath, anorexia, and prone to aspiration pneumonia. There is no cure for Megaesophagus thus a dog with the condition is only given supportive treatment including feeding in a vertical position several times a day and medications to alleviate the symptoms.

Breeds Commonly Affected: Irish Red and White Setter, Irish Setter, Irish Wolfhound
