Can dogs eat it?

Are mints and candy canes safe for dogs?

Last updated 23 September 2026 · How we write and check this

Short answer

Breath mints and candy canes are not safe treats for dogs. Many sugar-free mints contain xylitol, which can cause a dangerous drop in blood sugar. Candy canes are hard, sugary, and can splinter into sharp shards, and their plastic wrappers are often swallowed. Strong peppermint oil can also upset the stomach. Keep mint tins and holiday sweets out of reach.

Sugar-free mints and xylitol

Breath mints, sugar-free candy canes, and mint gum are among the most common sources of xylitol poisoning in dogs. A small tin of mints can contain a lot of xylitol, and small dogs are at particular risk. Signs such as vomiting, weakness, and wobbliness can appear within an hour.

Check the label, and call your vet or a pet poison helpline immediately if xylitol is listed.

Candy cane hazards

Regular candy canes are made from sugar and peppermint flavoring. The sugar can cause stomach upset, and the hard candy can break into sharp shards that cut the mouth or throat. Plastic wrappers are often swallowed along with the candy and can cause a blockage.

Candy canes hung on Christmas trees are at the perfect height for many dogs.

Peppermint oil and flavoring

Concentrated peppermint oil can irritate the stomach and cause vomiting and diarrhea if a dog licks or eats a significant amount. Essential oils used in diffusers or on skin are more concentrated than the flavoring in sweets and should be kept away from dogs.

Peppermint-scented cleaning products are another source to store safely.

Fresh breath the dog-safe way

Bad breath in dogs is usually a sign of dental disease rather than a minty-fresh problem to cover up. Daily brushing with dog toothpaste, dental chews designed for dogs, and regular dental checks are the effective options. Never use human toothpaste, which may contain xylitol. Your vet can check for tartar and gum disease at the annual visit.

Key takeaways

  • Sugar-free mints often contain xylitol.
  • Candy canes can splinter and their wrappers can cause blockages.
  • Concentrated peppermint oil can upset the stomach.
  • Bad breath needs dental care, not mints.
