Is Bougainvillea toxic to dogs?
We could not confirm Bougainvillea (Bougainvillea spp.) against an ASPCA entry, so we will not tell you it is safe. Treat it as unknown and call poison control if your dog has eaten some.
ASPCA Animal Poison Control, 24 hours: (888) 426-4435 (a consultation fee may apply), or call your own vet. Take a piece of the plant with you.
Signs that need a vet the same day whatever the plant: repeated vomiting, drooling that will not stop, swelling of the mouth or face, trouble breathing or swallowing, collapse, or a seizure.
What can still happen
Non-toxic means no poisonous compound, not no consequences. Any plant eaten in quantity can cause vomiting or loose stools simply as indigestible fibre, and potting mix carries its own risks — fertiliser granules, and the systemic insecticide many nursery plants arrive treated with. Not listed by ASPCA under this name. The real hazard is mechanical: the thorns are long and sharp and the sap can irritate a puncture wound.
If your dog is unwell after eating this plant, the plant is probably not the cause — which is a reason to call the vet, not to wait.
Is it toxic to people?
Yes, mildly. The same compound irritates human mouths and skin, so it is worth keeping Bougainvillea out of reach of a toddler and washing your hands after pruning. Serious harm to an adult is very unlikely.

Sources and how we checked
This species is not listed under a name we could resolve in ASPCA's database, so the record above comes from standard horticultural and veterinary references and is marked unconfirmed. We do not present an unconfirmed plant as safe. The full list is at aspca.org.
This is general information, not veterinary advice. Any animal that is actually unwell needs a vet, not a web page.
