Yes, squirrel corn is toxic to dogs. Its alkaloid-bearing foliage and especially its underground tubers can cause trembling, staggering and worse in quantity.

Also known as: Turkey Corn, Wild Bleeding Heart Relative, Dicentra canadensis · Dicentra canadensis

What makes it toxic

Isoquinoline alkaloids (the Dicentra family chemistry), most concentrated in the yellow tubers and also present in leaves and stems. They affect nerve signaling, causing progressive neuromuscular signs with larger doses.

Warning signs to watch for

Drooling, vomiting, muscle trembling, incoordination and lethargy within a few hours; serious tuber consumption can bring seizures or respiratory distress.

What to do if your dog eats it

Take the plant away and call your vet, urgently if tubers were dug up and eaten. Early decontamination prevents the dose from climbing further.

Common questions

Are the little yellow corns the most dangerous part?

Yes — the tubers concentrate the alkaloids, and dogs that dig are the classic exposure. Fencing off woodland garden beds is the simple fix.

Is it dangerous to just walk past it?

No, mere contact is harmless. The risk is chewing or eating, so a dog strolling through the patch is fine while a dog rooting in it is not.
