Is Buckeye Toxic to Dogs?
Also known as: Ohio Buckeye, Fetid Buckeye · Aesculus glabra
What makes it toxic
Aesculin and aescin-type saponins concentrated in the conker-like nuts and new shoots, acting as gastrointestinal and nervous system irritants.
Warning signs to watch for
Vomiting, diarrhea, drooling, lethargy and abdominal pain within hours; bigger ingestions can add tremors, incoordination and pale gums.
What to do if your dog eats it
Remove remaining plant material, offer water and call your vet with an estimate of how many nuts were eaten. Escalate to an ER for tremors or collapse.
Common questions
My dog ate buckeye nuts off the ground in fall — is that serious?
Yes, it can be. Fallen nuts are the most toxic part, and dogs commonly find them during autumn walks. Inducing vomiting early at a clinic is the usual approach.
Do cooked or roasted buckeyes become safe?
No. Heat does not reliably destroy the toxins, and pets should never be given buckeye products meant for folk use.
