Can Dogs Eat Mint?

Verdict: CAUTION — a few fresh mint leaves are safe; mint essential oil and mint candies are not.

Plain mint leaves (spearmint, peppermint) are not toxic to dogs. A few fresh leaves can even freshen breath. The danger comes from concentrated forms: mint essential oil is toxic, and mint candies, gum and toothpaste often contain xylitol, which is deadly to dogs.

What's safe

• A few fresh mint leaves from the garden — fine as an occasional treat.
• Mint is sometimes used in small amounts in dog treats and dental chews.

What's dangerous

• Mint essential oil — toxic even in small amounts; can cause liver damage and breathing problems. Keep diffusers away from dogs.
• Mint candies, gum, breath mints — almost always contain xylitol or sugar.
• Mint chocolate — chocolate is toxic on top of everything else.
• Mint toothpaste — human toothpaste is not for dogs; use vet-approved dog toothpaste.

Symptoms of a problem

• Vomiting, diarrhea
• Drooling
• Lethargy, weakness
• With xylitol: seizures, liver failure (emergency)

What to do

• If your dog ate mint leaves: no action needed, just watch.
• If your dog ate mint candy or gum: check the label for xylitol and call your vet immediately.
• If your dog got into essential oils: call your vet or poison control right away.
