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.
If your dog ate more than a safe amount
For a small accidental taste, watch for vomiting, diarrhoea, or signs of discomfort over the next few hours. For a large amount or if your dog is small or has existing health conditions, call your vet. When in doubt, call the ASPCA Animal Poison Control Center on (888) 426-4435.

Does size or breed matter?
Risk with mints scales with the quantity relative to body weight, so small and toy breeds reach a meaningful dose from a much smaller amount than large dogs. Always check for hidden risk ingredients (garlic, onion, xylitol, excess salt) in any prepared or shop-bought version rather than assuming the plain ingredient name on the label tells the whole story.
