How to Treat Diarrhea in Dogs?

The best way to treat diarrhea in dogs is to use the old tried and true Pepto-Bismol. If by chance you can’t get your puppy to take the liquid, which can get messy, try the tablets. You can give 1/4 tablet for every 20 pounds. If by chance this doens’t help, you may want to take him to the vet just to make sure it isn’t something more serious.
