At one time or another your dog may have a bout of vomiting. Usually he'll have eaten something disagreeable, eaten too much or too fast, exercised too soon after eating or any number of non-serious conditions. Vomiting may be a sign of a very minor problem. Or it may be a sign of something very serious.

Vomiting (emesis) is the act of expelling contents from the stomach through the mouth. It's a reflex act, involving a triggering stimulus (such as inflammation of the stomach), the central nervous system and abdominal muscles that work together to expel the contents from the stomach. There are multiple causes of vomiting. An occasional, infrequent isolated episode of vomiting is usually normal.

Vomiting is a symptom that can be caused by disorders of the gastrointestinal system (stomach and/or intestines) or it can be secondary to a disease from a different system (such as from cancer, kidney failure, diabetes, or infectious diseases).

This can make the diagnosis of the cause of the vomiting a challenge.

Vomiting can be defined as acute (sudden onset) or chronic (longer duration of one to two weeks). The severity or concurrence of other signs will determine the recommendation of specific diagnostic tests. Important considerations include monitoring the duration and frequency of the vomiting. If your pet vomits once then eats normally with no further vomiting, has a normal bowel movement and is acting playful, then the problem may resolve on its own. If the vomiting continues after your pet eats or if your pet acts lethargic, or doesn't want to eat, then medical attention is warranted.
