Can You Give Dogs Pepto Bismol for Vomiting? Answers Here!

Vomiting is a common symptom of many dog diseases, and most pet owners have had to deal with their dogs vomiting at some point. Irrespective of the cause of the vomiting, it is a distressing experience both for the dog and their owner. When your furry friend starts to vomit, your natural instinct is to help soothe them quickly, and one way out is by administering Pepto Bismol. But is Pepto Bismol safe for dogs?

Pepto Bismol, the brand name for bismuth subsalicylate, has been in existence for more than a century and is often used for managing common digestive issues such as heartburn, indigestion, upset stomach, and diarrhea in people. Since the problem symptoms in canines often match some of these human-associated digestive problems, it is logical to ask if Pepto Bismol can also be used for dogs to treat vomiting.

The Safety of Pepto Bismol for Dogs

Before giving Pepto Bismol to your dog, it is crucial to understand its safety, side effects, indications, and precautions. While Pepto Bismol is generally safe for dogs, it is not free from side effects. The following are the safety considerations to note:

Pepto Bismol in Dogs with Kidney or Liver Disease

Pepto Bismol should not be administered to dogs with liver or kidney disease without consulting with a vet. Since Pepto Bismol contains salicylates, a substance that can cause gastrointestinal bleeding and decreased kidney function, animals with these conditions are more susceptible to side effects.

Pepto Bismol for Puppies and Small Dogs

Pepto Bismol is generally unsafe for puppies and very small dogs. It is recommended to use a pediatric version of antacid medication, since too much Pepto Bismol can cause toxicity in small puppies and dogs.

Pepto Bismol Dosage for Dogs

Pepto Bismol dosage is dependent on the dog’s weight. Veterinarians recommend 0.5 to 1 ml per kilogram of bodyweight, which is about one teaspoon per 5 pounds of your dog’s bodyweight. Administering more than the recommended dosage could lead to abdominal pain, vomiting, and discoloration of the tongue.

Pepto Bismol Side Effects in Dogs

In rare cases, dogs may experience side effects after taking Pepto Bismol. Some of these side effects include constipation, stomach irritation, and changes in stool color. In addition, Pepto Bismol may affect a dog’s blood-clotting ability and cause blood in stool, vomit, or urine.

When Can Dogs Take Pepto Bismol for Vomiting?

Pepto Bismol is sometimes administered to dogs experiencing vomiting and stomach upsets. Here are the indications for Pepto Bismol for dogs:

Pepto Bismol for Dog’s Diarrhea

Diarrhea is one of the common issues that dogs suffer, and Pepto Bismol can help manage the symptoms. It is used to reduce inflammation in the gut, kill bacteria and viruses, and decrease the frequency and volume of stool.

Pepto Bismol for Dog’s Upset Stomach

Pepto Bismol can also be used to manage an upset stomach in canines by reducing nausea, calming the stomach acids and providing a soothing effect to prevent vomiting.

Alternatives to Pepto Bismol for Dogs

While Pepto Bismol is safe for most dogs, it might not be the most appropriate solution for some. Here are a few alternatives that can be considered;

Probiotic Supplements

Probiotic supplements help restore the balance of good bacteria in the gut when your dog is experiencing digestive issues. These supplements come in different forms – powders, liquids, and capsules – and may include L acidophilus, Bifidobacterium, and Lactobacillus species.

Prescription Medications

If your dog has an underlying and severe medical condition, your vet can prescribe medication to manage the vomiting. This medication will be tailored specifically for your dog and the medical issue causing the vomiting.

Hydration and Diet Adjustments

When your dog is experiencing vomiting, it is essential to manage their hydration and change their diet. Provide clean water and electrolytes and slowly introduce bland food such as boiled potatoes, rice, and low-fat meat to their diet.


Pepto Bismol is generally safe for dogs, but it is important to review its safety implications before administering it to your furry friend. It is essential to follow recommended dosage guidelines, and avoid administering it to small puppies, dogs with liver or kidney disease, and those on blood-thinning medication. Also, be on the lookout for signs of side effects such as blood in vomit or stool and immediately consult a vet in case these side effects occur. Finally, there are alternative approaches to managing vomiting in dogs, including hydration, probiotic supplements, and prescription medications, depending on the underlying condition causing the vomiting.
