The ASPCA lists mint (Mentha species) as toxic to dogs — the essential oils cause vomiting and diarrhea with large ingestions. A single leaf is unlikely to cause harm, but mint is not a herb to feed, and mint sweets and gum bring the xylitol question with them.
Don't feed it. If your dog has already eaten some, call your vet or poison control with the amount and the timing and follow their advice.
Never induce vomiting and never give any medicine unless a vet tells you to — it can do more damage than the poison. What we will and won't tell you.
Can cats eat mint? — Don't feed it to cats either.
No — mint should not be given to dogs. If yours has already eaten some, call your vet.

Watch for: Vomiting; Diarrhea or loose stools; Loss of appetite; Belly discomfort or unusual tiredness. Some signs lag by a day — call, don't wait.
The safe amount is none, as an occasional treat rather than a daily habit. Large amounts mainly cause stomach upset; if that doesn't settle within a day, call your vet.
