Will peppermint candy hurt dogs?

Most peppermint candies also contain the sweetener xylitol, which is highly toxic to dogs. Even small amounts of xylitol can induce liver failure in our four-legged family members, so this is a definite no-no! Some peppermint candies also contain chocolate, which is equally toxic in slightly higher doses.

Hard candies can also damage your dog’s teeth, cause a choking hazard, and scratch or get stuck in your dog’s digestive tract if not chewed properly, which can be life-threatening. The plastic wrap of peppermint candies is also a choking hazard and a danger to your dog’s insides.

Can I use peppermint oil with my dog?

Peppermint oil is an essential oil derived from the flowers and leaves of the peppermint plant. It has been used medicinally for centuries and can provide some of the same benefits that we’ve mentioned already, but not all essential oils are the same.

If you’re going to use essential oils with your dog, they must be of a high quality; all-natural, diluted, and specifically labeled as being made for dogs to ensure no unsafe or synthetic ingredients are in the oil. In fact, many of these types of oils are used in small quantities in dog treats and products like dog toothpaste.

However, lower-quality, synthetic essential oils can contain toxic ingredients that are extremely harmful to your dog, and those that are natural but undulated are far too strong.

There are certain things you should also never do with essential oils when it comes to your dog, no matter the quality of the oil.

Can I diffuse peppermint oil for my dog?

Can I use peppermint oil on my dog’s skin?

No, you should never apply essential oils to your pup’s skin, as it could cause irritation or even chemical burns, depending on the oil.
