Gastric motility disorder (abnormal movement of food through the stomach) Giardiasis (Giardia parasite infection) Pancreatitis (inflammation of the pancreas) Obstruction in the small intestine

Electrolytes (sodium, potassium, water) are important for your dog’s overall health. If your dog has been vomiting constantly, it may be dehydrated and have really low electrolyte levels. If your dog does not need to be hospitalized for the fast, carefully follow your vet’s instructions for the fast and reintroduction of food. Hospitalization would increase the cost of treatment.

Some dogs that throw up bile may also have stomachs that secrete too much stomach acid. This acid can irritate the stomach lining and cause vomiting. Your vet may prescribe a medication to reduce stomach acid secretion.

An endoscope can reach into the upper part of the small intestine. With an endoscope, your vet would gently nudge the obstruction free so that it could pass normally through the digestive tract.

Do not make more than one adjustment at a time. For example, if you change the type of food, do not change your dog’s feeding schedule at the same time.

Talk to your vet about leaving food out for your dog during the day while you’re not home. This strategy may work if your dog can graze on its food all day, rather than eating it all at once.

If you feed a late night meal, feeding multiple small meals during the day may not be necessary. Talk to you vet about how often you should feed your dog. A dog with bilious vomiting syndrome usually has no other common symptoms of vomiting, such as loss of appetite and weight loss. [10] X Research source
