Is Mylanta a Safe Antacid for My Pet Dog?

Is Mylanta a Safe Antacid for My Dog

Most products formulated for humans are not pet-friendly, making it quite a surprise when you stumble upon something that’s actually okay for your furry companion.

Mylanta happens to be one such exception. It is a well-known antacid that many of us have turned to for relief from heartburn and indigestion.

It actually works well for fiery discomfort in stomachs whether that’s human or canine.

Aluminum hydroxide and magnesium hydroxide are the two important active components in this antacid.

Basically, these are just complex names for substances that neutralize excess stomach acid.

Both are quite safe for your pets as long as given in the right dosage.

Just as you wouldn’t give your child a dose meant for an adult, you wouldn’t want to over or under-dose your dog with Mylanta.

What kind of antacid is safe for dogs?

When your four-legged friend experiences stomach discomfort, selecting the right antacid can bring them relief. 

Opt for antacids containing safe ingredients like calcium, magnesium, or aluminum compounds.

These elements help neutralize excess stomach acid and alleviate discomfort. 

Stay away from antacids with harmful additives like xylitol, which is toxic to dogs. 

In my experience, liquid antacids are easier to administer because you can easily mix them in your dog’s water.

But tablets can work too. If your furry friend is more finicky, try crushing the tablet and blending it with their meal.

Hey there, sorry to interrupt but I wanted to tell you about an online vet service I’ve been using for years.

How Much Mylanta Can You Give a Dog?

Generally, vets recommend around 1 to 2 teaspoons of Mylanta for every 10 pounds of your pet’s weight.

This can be given every 8 hours as needed. 

How Often Can I Give My Dog Mylanta?

Mylanta is typically safe, however, it’s a good idea to use it sparingly. 

To relieve your dog’s stomach issues, one dosage three times a day is sufficient. 

If the tummy problems continue, think about speaking with the vet rather than increasing the Mylanta dosage.

A persistent stomach ache might be an indication of a serious health problem.

What Are the Causes of Stomach Upset in Dogs?

Is your pet’s stomach singing an angry tune? It could be its way of letting you know that something’s not right with your pet’s digestion.

One common reason for stomach upset is indigestion.

Imagine your pup gobbling down food like there’s no tomorrow. If they’re not chewing properly, it can lead to digestion issues. 

Gas can also be a culprit. If your dog ate something their tummy didn’t agree with, it can cause discomfort. Gas often leaves their poor stomachs bloated.

Sometimes, it’s the food they eat. Sneaky table scraps might sound harmless, but some human foods can upset your pup’s belly.

Switching their diet suddenly can also cause tummy issues, much like when our stomachs rebel against a sudden change in our eating habits.

And then there are health factors. Infections, allergies, or even stress can make your dog’s tummy grumble.

What to Give a Dog With an Upset Stomach?

Serve your furry pal easily digestible food and consider adding ingredients that support better digestion.

Can You Give Dogs OTC Medicines for an Upset Stomach?

When your furry pal’s tummy is in turmoil and a trip to the vet isn’t an option yet, there are some over-the-counter (OTC) meds that you can rely on. 

But beware! Not all human remedies are dog-friendly.

Safe OTC medicines

There are a few OTC options that can lend a helping paw when your dog’s stomach is acting up.

Tums, Pepcid, and Zantac are just a few that are generally considered safe antacids for your canine friend.

They can provide temporary relief from excess stomach acid or indigestion.

If branded medicine is hard to come by, look for generic ones. You want to buy antacids that contain calcium carbonate, ranitidine, or famotidine.

OTC medicines to avoid

As I mentioned, not all OTC medicines that are good for humans are pet-friendly. You need to avoid meds like Pepto-Bismol.

This may surprise you especially since this antacid is so harmless to humans, But it contains Bismuth Subsalicylate, which isn’t recommended due to its toxicity risk in dogs. 

Another OTC medicine that you should avoid is certain variants of Mylanta. Some contain xylitol, which is safe for humans but decidedly dangerous for dogs.

What Are Some Natural Home Remedies to Help a Dog With an Upset Stomach?

When it comes to soothing your furry friend’s upset stomach, you might not need to look beyond your own kitchen for remedies that work wonders. From a brief fasting period to some trusted kitchen heroes, here are some natural solutions to help your pup find tummy comfort:


Giving your dog’s tummy a break by making them undergo a short fasting period can work like a reset button. This gives whatever it is that’s inside your pet’s system to leave, allowing their digestive system to settle.

Bland diet

A plain and simple diet can be a game-changer. Consider serving just cooked rice or unseasoned boiled chicken. These are easy on the stomach and provide much-needed comfort.


Canned pumpkin is a fiber-packed ingredient that can aid in digestion and offer relief. Make sure to get the variant that’s free of any sugary additives. You can also boil and mash your own from scratch. 


Probiotics are friends of your dog’s gut. Adding a dog-friendly probiotic supplement can help balance their belly’s good bacteria.

Plain yogurt

Plain yogurt with live active cultures can do wonders, acting as a probiotic-packed tummy soother. 

Boiled chicken broth

Clear broth is a good way to keep your pet fed and hydrated. A gentle and tasty option, plain boiled chicken broth can provide enough nourishment to get your pet through these tough times.


A bout of upset stomach can leave your pet feeling like they need to throw up all the time. A dash of freshly grated ginger can help combat that nausea.

Peppermint tea

Diluted caffeine-free peppermint tea might be your pup’s cup of tummy-calming tea. It soothes the roiling in the stomach and provides relief.

Rice water

The starchy water left after boiling rice can offer a mild, soothing sip for your pup’s tummy.


When your pet throws up and poops a lot, it’s easy to lose a lot of fluids. Staying hydrated is crucial. Always make sure that your furry pal has access to clean water.

Slippery elm

Slippery elm supplements can offer a soothing coating to your pup’s stomach lining, helping calm irritation.

What to Give a Dog With Acid Reflux?

What to Give a Dog With Acid Reflux besides mylanta

If your pet is sufering from acid reflux, you’d want to look for food options that are rich in fiber, healthy fats, or easily digestible proteins. 

Good choices include peeled, baked sweet potato for gentle digestion. You can also try pumpkin puree to soothe their poor tummies. 

Rice is a good neutral base that you can enhance with fish or other lean proteins like chicken or turkey.

A good bone broth is also a comforting treat. You can serve it on its own or you can pour it over rice.

For snacks, you can try bananas. This is a low-acid fruit that is rich in nutrients.

Frequently Asked Questions (FAQs)

Can you give Mylanta to a dog for upset stomach?

Yes, Mylanta may be used to treat upset stomachs in dogs, but you must first speak with your vet to establish the right dosage. If for any reason you’re not getting it from your vet, be sure that it does not include xylitol by looking at the ingredients list. This ingredient is toxic to dogs.

Can small dogs take Mylanta?

Small dogs can indeed take Mylanta, but the dosages need to be adjusted. Generally, the recommended dosage is 1 to 2 teaspoons of Mylanta for every 10 pounds of body weight. If your pet is smaller than 10 lbs, consult their veterinarian to establish the right amount for their needs.

How often can I give my dog antacid?

The frequency of administration to your dog depends on their specific condition. Generally, you can give your pet 1 to 2 teaspoons of antacid every 8 hours. However, your pet’s vet will know the right frequency depending on the severity of your pet’s condition and their individual needs.

Is Mylanta ok for dogs with kidney disease?

Antacids that contain calcium or aluminum compounds should not be used over an extended period of time since they may harm the kidneys. Before giving Mylanta or any other antacid to your dog if they have kidney-related illnesses, you should first visit a veterinarian.

Is Mylanta good for dogs diarrhea?

Yes, Mylanta can help dogs with diarrhea to some extent. It is still necessary for you to see your pet’s vet for a proper check-up because, while the antacid can provide relief for some symptoms, Mylanta does not treat the cause of diarrhea itself.
