Can dogs eat mints?

Caution — sugar-free mints contain xylitol

Regular sugar mints aren't toxic but sugar-free mints often contain xylitol, which is lethal to dogs.

The full picture

Regular sugared mints (Polo, Murray mints, Mintoes) aren't acutely toxic but are pure sugar — not dog food. The real danger is sugar-free mints: Trebor, Tic Tac, Mentos sugar-free, and most 'breath mints' contain xylitol. Check the ingredients on anything sugar-free. Even sugared mints in large amounts can upset a dog's stomach. Mint itself (fresh or dried mint leaves) is safe and sometimes used for dog breath — but not the sweet variety.

Risks to watch for
