No, bougainvillea is non-toxic to dogs. Chewing the papery bracts will not poison a dog — the thorns are the real problem.

Also known as: Paper Flower, Lesser Bougainvillea, Bougainvillea glabra · Bougainvillea glabra

What to do if your dog eats it

No toxicity action needed. For thorn injuries: pull out visible spines, clean the puncture and monitor for infection; a vet visit makes sense for deep, numerous or buried thorns.

Common questions

My dog ran through the bougainvillea hedge and is limping — poison?

No poison involved — check the paw for embedded thorns between the pads. Remove what you can see, clean it and have the vet extract any deeply buried spine.

Is the white or orange variety different from purple?

No — all bougainvillea colors are the same non-toxic genus. Color only changes the bract pigment, not the safety profile.
