Although the treatment varies depending on the underlying cause, the most common way to treat vomiting dogs is to withhold food and let the dog stop vomiting on its own, according to VCA Animal Hospitals. You may then feed a bland diet for a couple of days.
Do not withhold water from a vomiting dog, according to VCA Animal Hospitals. The most common bland diet recommended by veterinarians is a mix of boiled skinless chicken and white rice, which are easy for dogs to digest. Boiled potatoes may also be acceptable, as suggested by WebMD.
Severe vomiting may need to be treated with anti-emetic drugs, as reported by WebMD. Fluid therapy may also be required for dogs that are at risk of dehydration. If there is an underlying gastrointestinal infection causing the symptoms, your dog may be prescribed antibiotics. Dietary changes are also a common treatment for chronic vomiting.
Although most bouts of vomiting are not cause for concern, VCA Animal Hospitals recommends taking your dog to the veterinarian if the vomiting persists for more than a day or two. Your dog also needs veterinary treatment if there are other symptoms present, such as abdominal pain, fever, lethargy, diarrhea or loss of appetite. You should also contact a veterinarian immediately if the vomit contains blood or you know your dog has eaten something dangerous, such as chocolate or eating utensils.
