A not uncommon cause of vomiting in a dog is a sudden change of diet. Try never to change your dog’s diet too fast. For instance, if you’re switching kibble based on doctor’s orders or because of a change in your own feeding preferences, mix some of the new food with the old, gradually changing the proportion until more and more of the new food goes into your pet’s bowl. That will lessen the chances of the kind of gastric irritation or intestinal upset that could cause vomiting in a dog with a sensitive system.
