Is Spearmint toxic to dogs?

Mentha spicata

Toxic to dogs

Yes — spearmint is toxic to dogs according to the ASPCA. Keep it well away from any dog that chews plants; reactions can be significant. This classification follows the ASPCA Toxic and Non-Toxic Plant List. The ASPCA lists mint (Mentha species, including spearmint Mentha spicata) as TOXIC to cats, dogs, and horses, with the toxic principle being essential oils. Signs are vomiting and diarrhoea, especially with large ingestions; concentrated mint oils pose greater risk than a nibbled leaf. Keep pets from grazing it and contact a vet if a large amount is eaten.

What to do if your dog ate spearmint

  1. Remove any plant material from your dog's mouth and move spearmint 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 spearmint to the appointment so it can be treated correctly.

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