How about Pepto Bismal?

You need to check with your vet before giving your pet any medication but the answer on the Pepto Bismal question is usually yes.  You just need to adjust the dosage based on the size of your dog, your vet can tell you how much to give and how often.  If your dog just has diarrhea and is alert and eating you should follow orders from your vet and keep them on a bland diet until they are back to normal.  By the way, Pepto Bismal is not safe for cats in any dosage.
