Is Corn Mint toxic to dogs?

Mentha arvensis

Mildly toxic to dogs

Mildly. The ASPCA lists corn mint 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. The ASPCA lists Mentha species (mint, garden mint) as mildly toxic to cats and dogs, with gastrointestinal irritation — vomiting and diarrhoea — cited as the clinical signs. The essential oils, particularly menthol, are the irritating principle. Pennyroyal (Mentha pulegium) within the same genus is severely toxic and must not be confused with field mint.

What to do if your dog ate corn mint

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

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