Can dogs eat mint?
Only with care Best avoided. Large amounts of mint can cause vomiting and diarrhoea, and mint sweets, gum and toothpaste often contain xylitol.
Why
ASPCA lists mint as toxic to dogs because of its essential oils, with vomiting and diarrhoea after large amounts. Pet Poison Helpline says mint is not safe for dogs, mainly because mint products such as sweets, gum, toothpaste and mouthwash often contain xylitol, which can cause a dangerous drop in blood sugar and liver failure. A leaf or two of fresh mint is a small risk, but we use the more cautious verdict.
Signs to watch for
- Vomiting
- Diarrhoea
- Wobbliness, lethargy, tremors or seizures (if the product contained xylitol)
If your dog ate mint
If your dog ate a mint product, check the label for xylitol: if it is there, or you cannot tell, call your vet or an animal poison line now. A nibble of the garden plant needs nothing more than watching for an upset stomach.
If your dog has eaten something toxic
Call your vet or the nearest emergency vet now. Do not wait for signs, and do not make your dog sick unless a vet tells you to. Take the packet with you.

This is general guidance, your vet sets the actual schedule. Puppies, small dogs and dogs with a health condition can react to smaller amounts. Check with your own vet before changing what your dog eats.
