Q. My dog is trembling and has thrown up several times what could be the problem
A. Vomiting is a non specific symptom with many causes. The trembling may be due to nausea, pain or chill but it too, is a non specific symptom. Withhold food for 12-24 hours. Allow small amounts of water or unflavored PediaLyte. Resume feeding a bland diet (boiled boneless/skinless chicken and plain white rice) in small, frequent amounts waiting at least one hour between feedings. Once the vomiting stops, transition slowly to the regular diet. If the vomiting continues, see your veterinarian.
