Can Dogs Eat Mints For Bad Breath?

After a hard day at work, your dog happily greets you at the door with a slobbery kiss.

However, you catch a whiff of their not-so-pleasant breath and recoil from its pleasantries.

You wonder, what can alleviate your pup’s stinky breath?

You’ve heard about the mints people eat to freshen their breath, but can dogs have them too?

So, can dogs eat mints for bad breath?

Dogs can’t eat mints because they contain a small amount of xylitol.

Xylitol is a sugar alcohol that’s safe for humans to eat, but it’s toxic to dogs.

Even a tiny amount of xylitol causes your dog to have low blood sugar, which leads to vomiting, weakness, and loss of coordination.

In this article, we’ll explore everything you need to know about feeding mints to your dog, including the risks and benefits of doing so.


What Happens if my Dog Ate a Breath Mint?

You shouldn’t feed your dogs breath mints, either candies or leaves.

For instance, breath mint candies contain additives, sweeteners, and flavors harmful to your dog if ingested.

Moreover, even if you’re feeding them fresh mint leaves, there’s a chance that your pet could have an allergic reaction to the plant.

In most cases, if your dog ate a small amount of mint, they’ll be fine.

However, it’s always best to exercise caution and contact a veterinarian if you’re concerned about your pet’s health.

The following will happen if your dog ingests mint:

Xylitol Poisoning

Mints contain a small amount of xylitol, a sugar alcohol used as a sweetener in many products.

In large amounts, xylitol cause hypoglycemia (low blood sugar), seizures, and even liver failure in dogs.

A single mint contains such a small amount of xylitol that it’s unlikely to cause any problems.

Thus, within 15 minutes to an hour after eating a mint, your dog may experience vomiting and diarrhea.

If your pup ate a lot of mints or the mint was incredibly high in xylitol, they may have more serious symptoms like collapse, loss of coordination, and seizures.

These more severe reactions usually occur within 12 hours of ingestion.

Stomach Upset

Flavors and additives are often added to mints to give them their signature taste and smell.

While these ingredients are generally safe for people, they may not be safe for your pup.

For example, many mints contain essential oils like Mentha piperita (peppermint) oil or Mentha Viridis (spearmint) oil.

These oils cause an upset stomach in dogs.

Over consumption of mint leaves also lead to stomach upset in dogs.

If your dog ate a lot of mint leaves, it might experience vomiting and diarrhea.

In some cases, the mint leaves could obstruct their digestive system.

Allergic Reactions

Mints are plants from the Lamiaceae family, which includes basil, oregano, and sage.

If your dog is allergic to these plants, they may also be allergic to mint.

Allergic reactions range from mild (rash, hives, itching) to severe (trouble breathing, swelling of the face or throat).

Cavities in Dogs

Breath mints have sugar in them, which promotes plaque growth and leads to cavities in dogs.

If your dog eats mints regularly, it may be at a higher risk of developing cavities.

Thus, the problem of bad breath would escalate into a bigger dental issue.
