Quite often, vomiting is nothing more than an infection, or a stomach virus that will get better over the course of several days. However; if this behavior persists for long periods of time, it would be beneficial to have the dog looked at. If a tumor has grown in the abdomen, it could irritate the dog and cause this very unpleasant symptom. Surgery is usually possible, but it is quite expensive; and even then it won’t guarantee a full recovery.
