Every dog is different. Individual allergies and sensitivities are common — always introduce new foods in small amounts and watch for adverse reactions. This site is for informational purposes only and is not veterinary advice. Always consult your vet.
The Full Picture
A few fresh mint leaves (peppermint or spearmint) are safe for dogs and can help freshen breath. Mint contains vitamins A and C, and small amounts can aid digestion. However, pennyroyal mint is toxic to dogs and should never be given. Mint-flavored products like candy, gum, breath mints, and mouthwash often contain xylitol, which is extremely toxic to dogs. Mint essential oil is too concentrated and can cause vomiting, diarrhea, and liver damage. Stick to one or two fresh, plain mint leaves as an occasional treat.
What You Should Know
While mint is not outright toxic, there are important precautions to bear in mind before sharing it with your dog. Portion size matters, and certain preparations or varieties may be unsafe. If your dog has any existing health conditions, check with your vet first.
