The answer to this is a bit nuanced. In general, no, it isn’t advisable to give your dog Pepto-Bismol because the salicylates in it can lead to gastric bleeding. However, some vets may be OK with it on a limited-use basis. Chat with your personal vet to see if you can give your dog Pepto-Bismol as your vet knows your dog’s medical history best. They may offer a prescription like Tylan (tylosin) instead, which is approved for dog use.
