Q. Changed dog's food. Now throwing up and with diarrhea, what should I do?
JESSICA L DESROSIERS
A. Vomiting and diarrhea can occur if food is switched too quickly. Dogs generally need a slow changeover of foods over a period of a week or so to allow their guts and the gut bacteria to adjust. If there has only been one vomiting and diarrhea episode, removing the food for a few hours then feeding a bland diet of boiled chicken and plain rice can help soothe the stomach. You should then return to his old food and begin a gradual changeover of foods starting with 3 days of 75 old/25 new, 3 days of 50/50 and then 3 days of 25old/75 new. However if the vomiting and diarrhea symptoms do not improve, it may indicate something else causing his digestive distress and an appointment should be made with your local vet.
