Can dogs have peppermint? Only in a very limited way. A leaf or two of fresh peppermint is unlikely to hurt a healthy dog, but peppermint candy, candy canes, mints and gum are a different story: they’re sugary, can contain xylitol, and hard candy and wrappers can cause choking or blockages. Peppermint essential oil is the riskiest form of all. Here’s how to tell the safe forms from the dangerous ones, especially during the holidays.
Plain leaves in tiny amounts only. A small piece of fresh peppermint leaf is generally fine, but there’s no need to give it. Never give candy canes, peppermint candy, breath mints, sugar-free gum or peppermint oil. If your dog ate anything sugar-free, check for xylitol and call your vet right away.

Is Peppermint Safe for Dogs?
It depends on the form. Peppermint is a mint plant, and the ASPCA lists garden mint as toxic to dogs because of its essential oils, with vomiting and diarrhea mainly after large amounts. In practice, that means a leaf or two is low risk, while a mouthful of the plant or anything concentrated is not.
PetMD agrees that a small amount of plain fresh or dried peppermint is unlikely to harm most healthy dogs, but warns that candy, gum and essential oils are a real concern. One mint you should never allow is pennyroyal, a relative that can damage the liver. If you grow mint, make sure you know which kind is in your garden.
Peppermint Forms: What’s OK and What Isn’t
| Form | OK for Dogs? | Main Concern |
|---|---|---|
| Fresh or dried peppermint leaf | A tiny amount | Large amounts upset the stomach |
| Dog treats or dental chews with mint | Yes, as directed | Made for dogs in safe amounts |
| Plain peppermint tea (cooled, unsweetened) | Ask your vet | Not needed; never add sweeteners |
| Candy canes and peppermint hard candy | No | Sugar, choking, sharp shards, wrappers |
| Sugar-free mints and gum | No, emergency risk | Often contain xylitol |
| Peppermint bark and chocolate mints | No | Chocolate plus sugar and fat |
| Peppermint ice cream | No | Sugar, dairy, sometimes chocolate chips |
| Peppermint essential oil | No | Highly concentrated; risky to eat, lick or inhale |
| Wintergreen candy or oil | No | Contains salicylates, related to aspirin |
Can Dogs Eat Candy Canes?
No. A candy cane is essentially hard sugar with peppermint flavor, and it brings several problems at once. According to Pet Poison Helpline, sugar-free peppermint candy may contain xylitol, which can cause dangerously low blood sugar and liver failure in dogs. Even regular candy canes can:
- Splinter into sharp pieces that cut the mouth or throat.
- Get stuck as a whole piece in small dogs.
- Cause vomiting and diarrhea from the sugar load.
- Come with plastic wrappers that can block the intestines.
Candy canes hanging low on the Christmas tree are a common way dogs find them. Hang them high, or skip them on trees in homes with dogs.
Is Peppermint Oil Safe for Dogs?
Not for home use. Essential oils are highly concentrated, and dogs can be exposed by licking them, eating them, getting them on the skin, or breathing in strong diffusers. Problems can include drooling, vomiting, wobbliness and skin irritation, and breathing trouble in sensitive dogs. Pet Poison Helpline lists concentrated essential oils among the products that can poison pets.
- Never put peppermint oil on your dog’s skin or in their water as a flea or breath remedy.
- Keep oil bottles and diffusers out of reach, and use diffusers only in rooms your dog can leave.
- Ask your vet before using any essential oil product around pets.
Better Ways to Freshen Your Dog’s Breath
Many people reach for peppermint because of doggy breath. Mint only masks the smell. Bad breath usually comes from plaque, gum disease or other health problems, so it’s worth a vet check if it’s strong or new. Better options include:
- Brushing with a toothpaste made for dogs (never human toothpaste).
- Dental chews or treats your vet recommends.
- Crunchy, low-calorie snacks like carrots.
- A professional dental cleaning when needed.
Our dog bad breath guide explains the common causes and when to see a vet.
Puppies, Small Dogs and Sensitive Stomachs
Puppies and small dogs are most at risk from hard candy because pieces are large compared with their throats, and from xylitol because it takes less to poison them. Dogs with sensitive stomachs or a history of pancreatitis should skip sugary holiday treats entirely. For dog-safe holiday ideas, see our Christmas dog treats.
Is a small piece of peppermint leaf OK for dogs? Yes, a small piece is unlikely to cause problems. Large amounts can upset the stomach.
What should owners do first if a dog eats sugar-free mints or gum? Check the label for xylitol and call a vet right away. Don't wait for signs.
