A gastrostomy tube is a rubber feeding tube that passes directly into the stomach through a small opening in the skin and body wall of the dog's abdomen. It allows you to give food and water to your pet while it is recovering from a condition that prevents it from eating and drinking normally.
A pharyngostomy tube is a small rubber tube that enters the skin through a small incision in the side of the neck. The tube enters the esophagus, through the pharynx (back of the throat), allowing food to bypass the mouth and be delivered to the stomach. The pharyngostomy tube does not go all the way into the stomach because of the risk of complications that can occur.
