Yes, the Kentucky coffee tree is toxic to dogs. Raw seeds and their surrounding pod pulp contain cytisine, which acts on the nervous system like a nicotine overdose.

Also known as: American Coffee Berry, Coffeenut, Gymnocladus dioicus · Gymnocladus dioicus

What makes it toxic

Cytisine and related quinolizidine alkaloids, concentrated in the hard seeds and the sweet pulp within the pods. Chewing or swallowing either can poison a dog.

Warning signs to watch for

Vomiting, drooling and depression within a few hours, then rapid breathing, muscle tremors, twitching, incoordination and seizures in more serious exposures.

What to do if your dog eats it

Contact a vet immediately after seeds or pods are eaten. If it happened recently, professional vomiting induction and activated charcoal can intercept the toxin — another reason not to wait.

Common questions

Can a dog crack the hard seed pod?

Easily — dogs crack far harder objects, and the sweet pulp tempts chewing. A dog playing with fallen pods can swallow seeds whole, which also risks obstruction.

Are roasted seeds safe?

Roasting is what makes them usable for people, but that applies to deliberately prepared food, not dropped yard material. Keep all pods away from dogs.
