Q. 5 month old puppy has been sick 2 days with white foamy vomit and no appetite
A. Withhold food for 12-24 hours. Allow small amounts of water or unflavored PediaLyte. Resume feeding a bland diet (1:1 ratio of plain boiled boneless chicken and plain white rice). Feed in small, frequent amounts waiting at least one hour between feedings. Serve it warmed or mix in a teaspoon or two of baby food to stimulate the appetite. If the vomiting stops, transition slowly to the regular diet. If not, see your veterinarian.
