Is Boston Ivy Toxic to Dogs?
Also known as: Japanese Creeper, Bostonian Ivy, Grape Ivy (colloquial), Parthenocissus tricuspidata · Parthenocissus tricuspidata
What makes it toxic
Insoluble calcium oxalate raphides concentrated in leaves and berries, which tear the lining of the mouth and digestive tract on contact.
Warning signs to watch for
Immediate oral pain and drooling, head shaking, pawing at the mouth, vomiting and diarrhea. Berry-heavy meals produce the worst GI signs.
What to do if your dog eats it
Flush the mouth with water, remove leftover leaves or berries and offer water. Contact your vet if vomiting is repeated or lasts more than a few hours, and watch breathing closely in any severe reaction.
Common questions
My dog ate berries off the ivy wall — how bad is that?
Expect mouth pain plus vomiting or diarrhea. It is rarely life-threatening, but a big berry haul deserves a vet call, especially for a small dog.
Is Virginia creeper equally toxic?
Yes — its close relative Parthenocissus quinquefolia carries the same oxalate crystals and irritant berries. Treat both climbers as off-limits for dogs.
