Pepto Bismol can be used to treat diarrhea in most dogs, according to PetCareRX. Consult a veterinarian to determine proper dosage and to make sure the treatment is safe for a particular dog. Although it is safe for dogs, Pepto Bismol is not safe for cats.
Pepto Bismol is not safe for pregnant or nursing dogs, ones with bleeding disorders or allergies to ingredients in the medication, or dogs on medications that may interact with ingredients in Pepto Bismol, warns PetCareRX. Bring the dog to the vet if she has diarrhea for more than a day or exhibits other symptoms, such as vomiting, loss of appetite, dark stools or lethargy.
