Reasons for Dogs to Vomit

by Yvette Sajem

Overview

It is common for your dog to vomit. If he eats too fast, exercises too hard or munches on some grass in the backyard, he often will end up getting sick. However, if your dog's vomiting is repeated or is accompanied by other symptoms of illness, you should call your veterinarian immediately. It will probably turn out to be something simple--like a dietary indiscretion or gastritis--but there could be a more serious problem.
