Your veterinarian will keep your dog in the hospital if it is severely dehydrated due to chronic vomiting and diarrhea. There, your pet will be given fluids intravenously. (It should not be fed by mouth while it is still vomiting.) If your pet is severely underweight, your veterinarian may insert a stomach tube to feed your pet.
Depending on the underlying cause, he or she will change your pet’s diet, which is called elimination diets. Medication is also available depending on the underlying cause of the disease.
You will be advised to bring the dog back for a follow-up appointment. If the animal is still very ill or on strong medication, less time will pass between check-ups. As your pet stabilizes, your veterinarian will want to examine your pet less often.
You will also work with the veterinarian to formulate a new diet and assess the results on a continual basis until there are no more signs of illness.
