causes of dog regurgitation
Common Causes of Regurgitation. A disease of the esophagus is the most common cause of regurgitation in a pet, and is either the result of an obstruction or a motility problem. The esophagus can be obstructed by a foreign body, stricture, vascular abnormality, or, less commonly, a tumor.
1 In cases of regurgitation, it happens without warning. 2  Thereâs a difference between the appearance of vomitus, regurgitus, and a third variation -- expectorate.  The causes of chronic vomiting or regurgitating are also different. Vomiting is usually tied to the diet, dietary indiscretion, possibly a toxin or foreign body, or a developing condition like inflammatory bowel disease. Regurgitation happens for reasons unrelated to the diet or health of the lower GI tract.
