Regurgitation is the relatively effortless expulsion of undigested food, without retching. Regurgitating should not be confused with vomiting. Vomiting is the forceful expulsion of stomach contents, preceded by drooling and retching.
Relatively effortless expulsion of undigested food, without retching.
Regurgitation occurs because the esophagus is physically blocked or because it lacks peristaltic activity. In either case, the food accumulates until the esophagus is overloaded, after which the food is passively expelled.
The sudden onset of regurgitation in a previously healthy dog is almost certainly due to a foreign object caught in the esophagus. Constant drooling indicates that the dog cannot swallow saliva.
Chronic regurgitation (this may come and go, but appears to get worse) suggests a partial obstruction caused by megaesophagus, stricture, or tumor.
