Causes of Chronic Vomiting in Dogs Chronic vomiting can be caused by diseases of the gastrointestinal tract or can occur secondary to other systemic diseases. It is important to try to establish the cause of chronic vomiting.
Because there are so many causes of vomiting, the treatment will vary (See Table 1: Causes, Diagnosis and Treatment of Vomiting in Dogs). In many cases of vomiting in dogs, it is recommended to withhold food for at least 24 hours, and provide small amounts of water frequently. Then, a bland diet such as boiled hamburger and rice is offered in small amounts.
