Is Stinging Nettle Toxic to Dogs?
Also known as: Common Nettle, Burn Nettle, Urtica dioica · Urtica dioica
What makes it toxic
Stinging hairs that inject a cocktail of formic acid, histamine, acetylcholine and serotonin on contact. Dogs get stung on the muzzle, paws and belly, and in the mouth if they bite.
Warning signs to watch for
Sudden yelping, head shaking, drooling, paw licking, red raised welts and swelling where contact occurred, plus possible vomiting after biting leaves.
What to do if your dog eats it
Wash the area with cool water and soap, apply a cold pack and keep the dog from licking. Call your vet if facial swelling affects breathing or the dog stays distressed for more than an hour.
Common questions
My dog rolled in nettles — what now?
Rinse the coat thoroughly, use a cool compress on welts and keep paws out of reach. Most reactions fade within hours.
Are young nettle shoots as potent?
Yes, fresh growth stings just as well. Clear nettles from paths and play areas rather than relying on the season.
Can the sting cause an allergic reaction?
Occasionally a dog reacts more strongly, with widespread hives. That pattern warrants a vet visit the same day.
