Why Is My Dog Throwing Up?

Vomiting can occur directly after eating or at any time after that. Vomiting is often preceded by signs of drooling, nausea, licking of the lips, and excessive swallowing.

When a dog generally vomits food or objects come typically from the small intestine or stomach because vomiting is an active process. When your dog vomits, you will see partially digested food along with the clear liquid in the vomit.

There is a crucial point to keep in mind that vomiting and regurgitation are two different things. Regurgitation is a mild expulsion of undigested food from the dog’s esophagus through the mouth. It is considered as a passive process.

In vomiting, abdominal components are present; on the other hand, regurgitation does not imply abdominal heaving.

Your dog can start throwing up for many reasons, usually when he eats something that doesn’t fit his stomach or when the dog overeats, and when there is an infection present in his stomach.

A dog can also vomit when he ingests something irritating, such as grass, spoiled or rotten food, paper, toys, and bones. The white foam in the vomit indicates that your dog is trying to throw something foreign like a toy or a toxic substance.

White foam vomit can also be a sign of kennel cough, especially when experienced in conjunction with eye discharge, runny nose, and dry cough.

Chocolate, onions, and grapes are some of the most dangerous foods for dogs. If you have a pet that loves to dig in the trash, food poisoning is a likely cause of vomiting.
