Can You Give a Dog Pepto-Bismol?

Pepto-Bismol (bismuth subsalicylate) is a well-known over-the-counter medication for treating stomach upset and diarrhea in humans. Pet owners often wonder if Pepto-Bismol can be given to their dogs during episodes of mild gastrointestinal distress. While Pepto-Bismol can be safe for dogs in small doses, it is crucial to understand the specific dosage, risks, and the circumstances under which its use is appropriate.

How Does Pepto-Bismol Work?

The active ingredient in Pepto-Bismol, bismuth subsalicylate, belongs to the salicylate family. It works by coating the stomach lining, reducing inflammation, and slowing down the growth of certain bacteria that cause digestive upset. However, because these effects were optimized for human physiology, caution must be exercised when using this medication in dogs.

Pepto-Bismol Dosage for Dogs

The safe amount of Pepto-Bismol for dogs is highly dependent on their body weight and overall health status. Never exceed the dosage recommended by a veterinarian, as overdose can cause serious side effects.

  • For most dogs, the recommended dosage is 1 teaspoon (5 ml) per 10 pounds of body weight, given orally every 6–8 hours.
  • Alternatively, dosage may be calculated as 0.25–2 ml per kg (0.1–0.9 ml per lb) of body weight. Veterinarians often use the original-strength liquid formula for accuracy.
  • Pepto-Bismol should be used only for short-term relief—never administer it for longer than 1–2 days without veterinary supervision.
  • Measure the medication precisely using a dosing syringe or marked spoon—never use household spoons, which are unreliable.
  • Always consult your veterinarian before giving any medication and do not double up on dosages.

10 lbs (4.5 kg)5 ml1 tsp
20 lbs (9 kg)10 ml2 tsp
30 lbs (13.5 kg)15 ml3 tsp
40 lbs (18 kg)20 ml4 tsp

Note: Always verify the correct dosage for your dog with your veterinarian.

Safe Administration Tips

  • Use a plastic needleless syringe for easier dosing; gently inject the medication into the side of your dog’s mouth.
  • Hold your dog’s snout for a few seconds after dosing to ensure the medicine is swallowed.
  • Do not give Pepto-Bismol within two hours of other medications to prevent possible interactions.
  • Watch for stool discoloration (blackened stool)—this is a common side effect due to the bismuth compound.

When Pepto-Bismol is NOT Appropriate

Pepto-Bismol should only be used for mild, occasional digestive upset. In more serious scenarios, direct veterinary care is required.

  • Do not give Pepto-Bismol to dogs with:
    • Persistent or severe diarrhea (>2 days)
    • Repeated vomiting, blood in stool
    • Known aspirin allergy or aspirin sensitivities
    • Bleeding disorders, or taking blood-thinning medications
    • Pregnant or nursing dogs
    • Dogs on other medications (risk of interactions)
    • Cats, as it is toxic to them

If your dog ingested something toxic, is lethargic, has abdominal pain, or you notice additional worrying symptoms, seek veterinary attention immediately.

Possible Side Effects of Pepto-Bismol in Dogs

  • Black or dark stools—normal, but can mask blood in stool
  • Stomach bleeding—rare but serious if overdosed or used in sensitive dogs
  • Vomiting or worsening gastrointestinal signs
  • Potential interactions with other drugs, especially NSAIDs, steroids, and anticoagulants

If any of the above occur, stop the medication and call your veterinarian right away.

How Fast Does Pepto-Bismol Work for Dogs?

When appropriate, Pepto-Bismol typically starts working within 1–3 hours to reduce mild symptoms. If no improvement is seen within 24 hours, or symptoms worsen, discontinue use and contact your veterinarian.

Alternatives to Pepto-Bismol for Upset Stomach in Dogs

Veterinarians may prefer other medications or supportive care, depending on the cause of digestive distress. Pepto-Bismol is not always the best solution; alternative therapies may include:

  • Bland diet—shredded chicken, white rice, bone broth, pumpkin, potatoes, oatmeal, plain yogurt, eggs, or white fish
  • Antacid medications designed for dogs (e.g., famotidine, sucralfate)
  • Prescription antacids like Corrective Suspension for more serious issues
  • Probiotics—promote healthy gut flora

Always consult your veterinarian before selecting a treatment.

Cost of Pepto-Bismol

  • Original Pepto-Bismol: typically around $5 per bottle
  • Other forms (chewable tablets, extra strength) may vary in price
