Bismuth subsalicylate—most commonly known as Pepto-Bismol—is an antidiarrheal, or diarrhea medication. Most people use it to treat side effects from ingesting too much food and drink. Common symptoms it can tackle include heartburn, indigestion, diarrhea, and nausea.

Humans aren’t the only ones who can suffer from these unpleasant symptoms, though; our pets can, too. When it comes to settling Fido’s stomach, some people turn to over-the-counter (OTC) remedies originally designed for humans, like Benadryl or even Pepto-Bismol. Naturally, plenty of pet parents have questions about using Pepto-Bismol for dogs, such as: Is it safe? What do the vets say?

How Do You Settle a Dog’s Upset Stomach?

There are plenty of ways to settle an upset pooch’s digestive problems. Is Pepto-Bismol one such way? According to experts, yes, Pepto-Bismol can help settle your pet’s upset stomach, reduce gas, or even alleviate diarrhea.

Unlike many OTC medications, the U.S. Food and Drug Administration (FDA) has approved the use of Pepto-Bismol for dogs. That’s why vets sometimes use this drug to treat diarrhea and indigestion in our canine friends.

How Many mL of Pepto Can I Give my Dog?

It’s always best to consult a licensed veterinarian before giving your pet any medication, even if it’s FDA-approved and OTC. This consultation is especially important if your pet has an underlying medical condition or is already taking other drugs (prescription or OTC).

That being said, Plumb’s Veterinary Medication Guides lists the following as common veterinary dosage forms:

  • Oral paste: 5%, 10%, 20%
  • Oral suspension: 1.75%
  • Tablets and caplets: 262 mg

Liquid Dosage

According to the American Kennel Club, it’s generally recommended to give a regular-strength liquid dosage of 1 teaspoon per 10 pounds every 6 to 8 hours. For example, a 25-pound pooch could take 2.5 teaspoons every 6-to-8-hour period.

Tablet Dosage

According to Healthy Paws Pet Insurance, it’s generally acceptable to give a regular-strength chewable tablet dosage of 8.5 mg per pound.
