Dogs can eat small amounts of plain peppermint leaves, but larger quantities or other forms like candies and oils pose risks. Fresh peppermint is generally non-toxic in moderation for most healthy dogs, though it may cause stomach upset. Always consult a vet before offering it, especially for puppies, seniors, or dogs with health issues.
Safe Forms
- Tiny portions of fresh or dried peppermint leaves may freshen breath or aid mild digestion without harm.
- Dog-specific treats or dental chews with peppermint are formulated safely.
Unsafe Forms
Peppermint candies, gum, and chocolate often contain xylitol, which is highly toxic and can cause hypoglycemia or liver failure. Essential oils and extracts irritate the mouth, stomach, or skin and may lead to seizures in high doses. Pennyroyal mint is outright poisonous.
Risks and Precautions
Excess peppermint can trigger vomiting, diarrhea, or irritation, particularly in sensitive dogs. Avoid it for dogs on medications, with GI issues, or during pregnancy. If ingestion occurs, monitor closely and contact a vet or poison hotline.
