Regurgitation in Dogs

Regurgitation is the backward flow or effortless evacuation of fluid, mucus, or undigested food from the esophagus. Regurgitation refers to the process in which the dog's stomach contents (i.e., food) move backwards up the esophageal track and into the mouth without retching. Unlike vomiting, regurgitation is not accompanied by nausea and does not involve forceful abdominal contractions. It is a symptom of esophageal disease and not a disorder in itself.

Under normal conditions, stomach contents are not supposed to be regurgitated because of gravity and the natural peristaltic movement of the gastrointestinal tract.

When a dog is regurgitating its stomach contents, this could signal a blockage anywhere in the intestinal tract that does not allow the contents to move the natural way hence the regurgitation.

This medical condition can be congenital (inherited) or acquired from a variety of causes. Fortunately, modifications to the animal's diet, in conjunction with medication, will correct the condition.

Common symptoms associated with regurgitation include:





Weight loss

Runny nose

Difficulty swallowing

Bad breath (halitosis)

A ravenous appetite

Swelling in the neck

Increased breathing noises
