A. Diet changes done too quickly can sometimes cause vomiting and diarrhea as it takes a little while for the intestinal flora to adjust. However, if the diet change made symptoms worse or if the vomiting has continued for a prolonged period of time, it is a good idea to schedule a veterinary checkup to make sure there is not another underlying cause of illness causing it. Some food allergies may also cause vomiting or allergy symptoms such as wheat, corn, soy and certain protein products such as beef and chicken.
