what color is dog bile on an empty stomach
Why Does My Dog... Vomit Yellow Foam? In most cases, yellow foam indicates that the dog's stomach is relatively empty of food. The yellow color comes from bile, a digestive fluid that's produced in the liver, stored in the gall bladder and then released into the small intestine just below the stomach. A dog may vomit yellow foam simply because his stomach is empty and the bile can be irritating. If your dog is otherwise healthy â and he's eating and defecating normally â it may help to reduce the time in between meals. But this doesnât mean that your dog should be fed more.
