Is Jack-in-the-Pulpit Toxic to Dogs?
Also known as: Arisaema triphyllum, Indian Turnip, Bog Onion · Arisaema triphyllum
What makes it toxic
Insoluble calcium oxalate raphides concentrated in the corm. Chewing ruptures cells and drives the needle crystals into the lining of the mouth and digestive tract.
Warning signs to watch for
Sudden drooling, oral pain and pawing at the mouth, followed by possible vomiting and mild diarrhea. Signs fade within hours once the crystals are rinsed away.
What to do if your dog eats it
Rinse the dog’s mouth thoroughly with water and offer fresh water to drink. Contact your vet only if drooling, vomiting or swelling lasts beyond a few hours.
Common questions
My dog chewed the root in the woods — will it be OK?
Almost certainly. Expect strong mouth pain and drooling for an hour or two; a vet visit is only needed if swelling interferes with breathing or vomiting will not stop.
Does cooking make the root safe like Native American use suggests?
Yes for humans — heat breaks down the crystals. That does not apply to a dog chewing a raw plant, so keep woodland walks supervised where it grows.
