If your pet vomits once or twice during the day, food and water should be withheld from your pet for the remainder of the day.
If there is no additional vomiting offer small amounts of food and water the next morning. When starting to feed your pet you should feed small but frequent meals of a bland diet (ie: boiled ground hamburger / chicken and rice).
Should the vomiting persist, worsen or re-occur, or contain blood, seek immediate veterinary care.
If you suspect ingestion of a foreign object or toxin by your pet, seek immediate veterinarian care.
