Is Peppermint toxic to dogs?

Mentha piperita

Mildly toxic to dogs

Mildly. The ASPCA lists peppermint as mildly toxic to dogs — a chewing dog typically gets mouth irritation, drooling, and vomiting rather than a medical emergency, but it is still best kept out of reach. This classification follows the ASPCA Toxic and Non-Toxic Plant List. ASPCA lists Mentha (mint) as toxic to cats, dogs, and horses. The essential oils — primarily menthol and menthone — can cause vomiting, diarrhea, and weakness, particularly in cats, which cannot efficiently metabolize phenolic compounds. The plant itself in small amounts presents lower risk than concentrated oils, but pets should be kept away. Seek veterinary advice if ingestion is suspected.

What to do if your dog ate peppermint

  1. Remove any plant material from your dog's mouth and move peppermint out of reach.
  2. Note how much was eaten and when, and watch for drooling, vomiting, or lethargy.
  3. Do not induce vomiting unless a vet or poison-control specialist instructs you to.
  4. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice.
  5. Bring a leaf or photo of peppermint to the appointment so it can be treated correctly.

General guidance, not veterinary advice. If you think your dog has eaten peppermint, contact your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 — do not wait for symptoms to worsen.
