How does it help dogs?

You might be wondering how Pepto-Bismol can help your dog, and the truth is that it can help with different symptoms and problems. If your dog has mild diarrhea, indigestion, or gas, Pepto-Bismol can ease or completely stop these problems. However, this should never be your first option.

Suppose you find yourself in a situation where your dogs have gastrointestinal problems, and you probably will since dogs have sensitive stomachs. In that case, vets recommend these three steps - calling them, adding pumpkin, or just doing nothing.

Calling your vet

Contacting your vet and asking for advice is not the first thing you should do. You can observe your dog’s symptoms, and if they are not gone in 24 hours, you should call your vet and ask for advice.

Adding plain canned pumpkin

Depending on your dog’s size, you can add plain canned pumpkin to their everyday meal. Pumpkin contains fiber that will harden your dog’s stool.

Doing nothing

Most dog stomach problems will go away on their own. Sometimes, just doing nothing is the best possible course of action. Give your dog plenty of water and observe their symptoms.

Are there any alternatives?

Pepto-Bismol is not the only over-the-counter medication that is safe for dogs. There are plenty of safer options, and vets will most likely tell you about them. Pepto-Bismol can cause bleeding in rare cases, and if your dog’s stool turns black, the bleeding might be hard to notice. The possible alternatives are Pepcid and Imodium.


Pepcid is an OTC medication for stomach relief. The main difference is it has different active ingredients. It is a safe option for dog stomach problems, and vets will probably tell you to use that instead of Pepto. Pepcid should be administered like this - 5 mg per 10 pounds of dog weight.


Imodium is yet another OTC medication often given to dogs and “prescribed” for diarrhea. It is a loperamide-based drug that should be administered like this - 1 mg for 20 pounds of dog’s body weight. Check with your vet first if Imodium is specifically safe for your dog.
