You can give your pup famotidine, also known as Pepcid, to help soothe their upset tummy. Famotidine is an H2 receptor antagonist that decreases stomach acid production. It’s commonly used in veterinary medicine to treat stomach ulcers, acid reflux, and gastroenteritis in dogs.

Uses of Famotidine for Dogs

Uses of Famotidine for Dogs
As your dog’s trusted veterinarian, I want to tell you how famotidine treats various stomach issues in dogs. We often prescribe this medication for ulcers, acid reflux, and certain infections of the gastrointestinal tract, as it reduces the production of stomach acid that can worsen these conditions.

Famotidine can provide relief by decreasing gastric acid secretion in dogs suffering from stomach and intestinal ulcers. It helps reduce acid reflux by lowering the amount of acid made in the stomach. For some bacterial infections of the digestive system, famotidine is useful because it can inhibit the growth of bacteria that rely on an acidic environment.

By neutralizing excess stomach acid, famotidine eases discomfort and allows the stomach lining to heal. With its antacid properties, famotidine is an effective treatment option for several common stomach ailments in canines when prescribed by a veterinarian.

Monitoring the dosage carefully is important, as famotidine can potentially interact with some other medications. Overall, famotidine is a helpful medicine for managing gastric acid-related health issues in dogs.

Stomach Issues

Instead of wondering how much Pepcid to give your dog, consult with your veterinarian, who can diagnose the root cause and recommend the most suitable treatment for Fido’s upset stomach. Pepcid alternatives like famotidine may help, but risks like gastric bleeding from ingredients in products such as Pepto-Bismol underscore the importance of veterinary advice for managing diarrhea and other canine stomach issues.

Probiotics could supplement treatment, but your vet can best determine safe dosages and appropriate options for your pup’s health.


Given famotidine’s effectiveness against gastric ulcers, the vet may recommend starting your dog on 5mg twice daily.

  1. Give the medication on an empty stomach.
  2. Avoid food for 1 hour after dosing.
  3. Stick to the prescribed regimen.
  4. Limit strenuous activity and stress.
  5. Provide soft, bland food.

By following these steps and your vet’s guidance, you can get your dog’s ulcer under control and prevent future flare-ups. With time and care, your furry friend will be wagging their tail happily once more.


Hey, Pepcid can also help your pup with acid reflux in doses of 0.25 to 0.5 mg per pound once or twice daily, but don’t give it long term without the vet’s approval.

Frequency Dosage
Once daily 0.25-0.5 mg/lb
Twice daily 0.25-0.5 mg/lb

Administering famotidine for reflux requires veterinary guidance on dosage and duration. Consider alternatives like dietary changes if reflux continues. Your veterinarian knows best how to relieve your dog’s acid reflux safely.


Your beloved pup could be suffering from an infection. Get your dog checked out as famotidine may provide some relief, but only a veterinarian can properly diagnose and treat their condition. Be sure to follow your veterinarian’s dosage instructions carefully and monitor your dog for side effects like vomiting or diarrhea.

How is Famotidine Supplied?

The famotidine your veterinarian prescribed comes in various strengths to properly dose your pup. Famotidine is available in 10mg, 20mg, and 40mg tablets. Some brands offer a peppermint flavored chewable tablet which can help mask the bitter taste.

Your vet may also prescribe an oral suspension containing 50mg/5mL for easier dosing flexibility.

Here are some key tips for administering famotidine:

  1. Give famotidine on an empty stomach about 1 hour before meals for maximum absorption.

As someone who loves their furry friend, it is so important to help prevent unintended Pepcid exposure.

First, check with your veterinarian about any potential drug interactions. Pepcid can interact with some antibiotics, antifungals, seizure medications, and drugs that affect the immune system.

Be sure to provide a full list of any other medications or supplements your dog is taking. Also, use caution if your dog has liver or kidney problems, as the dosage may need to be adjusted.

It’s best to avoid Pepcid in pregnant or nursing dogs until you consult your vet.

Carefully follow your vet’s dosage instructions based on your dog’s weight and medical needs.

With some care and your veterinarian’s guidance, Pepcid can be used safely in dogs. But making medication safety a priority ensures your dog’s health and well-being.

Allergic Reactions and Sensitivity

Allergic Reactions and Sensitivity
Let’s move on from discussing drug interactions to considering allergic reactions and sensitivity when giving famotidine (Pepcid) to dogs. You’ll want to keep an eye out for any signs of an allergic reaction or sensitivity after administering this medication.

Some dogs may experience hives, facial swelling, or difficulty breathing. If you observe any of these symptoms, stop giving the Pepcid right away and contact your veterinarian.

When giving famotidine, it’s also important to pay close attention to the dosage. Giving too much can potentially cause adverse effects. Carefully follow your vet’s instructions and monitor how your dog responds.

Imodium for Dogs

Imodium for Dogs
You’d want to consult your vet first, but the typical dosage of Imodium for a dog is one 2-milligram pill per 40 pounds of body weight, up to 2-3 times a day for no more than two days.

Imodium can help manage diarrhea in dogs when used cautiously under a vet’s guidance.

  • Only use the generic, regular strength Imodium; never use Imodium AD.
  • Calculate the correct dose based on your dog’s weight as mentioned above. Do not exceed.
  • Give with food to reduce stomach upset. Liquid forms may be easier for some dogs.
  • Monitor your dog closely and stop use if symptoms persist or worsen.

While Imodium can provide some relief, persistent diarrhea may need different treatment. Ensure your dog stays hydrated and contact your vet if the diarrhea lasts more than 48 hours or is accompanied by other symptoms like lethargy or vomiting.

They can recommend safer anti-diarrheal alternatives tailored to your dog’s needs and determine if an underlying condition requires medication or diet changes for long-term diarrhea management. With a vet’s guidance, Imodium can provide temporary relief, but it does not treat the root cause of canine diarrhea.
