Can I Give My Dog Pepto-Bismol?

Yes, with care
Bismuth subsalicylate is commonly referenced for dogs at published doses. Published guidance for dogs: 1 tsp (5 mL) per 10 lb, every 8h, max 2 days. Contains a salicylate (aspirin relative). Short courses only; black stools expected (can mask GI-bleed signs). Skip if on other NSAIDs or steroids.

Cats are different

Do not carry this answer over to your cat: for cats, Bismuth subsalicylate falls under “do not give at home.” Species handle drugs differently, and the dog answer on this page applies to dogs only.

About Bismuth subsalicylate

Bismuth subsalicylate is a gastrointestinal medication. You will see it sold as Pepto-Bismol, Kaopectate (current) and store-brand equivalents, and the label strength on the box is what matters for the math, not the brand. Reference data on this page reflects published veterinary sources, not a prescription for your dog.

What to have ready when you call the vet

Whether you are confirming a dose or reporting that your dog already got into something, the call goes faster with four facts ready: your dog's current weight, the exact product name and strength from the label, how much was given or eaten, and roughly when. With those, most clinics can answer in one call.

The safe habit

Confirm any medication decision with your veterinarian, who knows your dog's health history and other medications. VetDose shows published reference data, not prescriptions.
