Dog's with GOLPP also have reduced esophageal function. The esophagus is essentially "the tube" between the mouth and the stomach and moves food from the mouth to the stomach. When the esophagus becomes weak and widened, food does not move as quickly from the mouth to the stomach. The risk of slow food movement is the backward flow of food/fluid as well as acid back into the throat. This can lead to heartburn, regurgitation of food and aspiration pneumonia.
