This is what it says in my dog owners medical book:
SPORADIC VOMITING
Sometimes a dog vomits off and on over a period of days or weeks. There is no relationship to meals. The appetite is poor. The dog has a haggard look and appears listless. Suspect liver or kidney disease, or an illness such as chronic gastritis, stomach or duodenal ulcer, a heavy worm infestation or diabetes mellitus. In an older dog, supect a gastric tumor. A veterinary checkup is in order.
PERSISTENT VOMITING
If the dog vomits or retches repeatedly, bringing up a frothy, clear fluid, this suggests a stomach irritation such as acute gastritis. However, persistent vomiting also occurs with life-threatening disease such as acute pancreatitis, gastric outflow obstruction, intestinal obstruction and peritonitis. Persistent retching without bringing up any vomitus is typical of bloat. Repeated vomiting along with diarrhea suggests acute infectious enteritis. |
