Yes, cyclamen is toxic to dogs. Leaf and flower nibbles mean stomach upset, but the underground tuber can cause heart rhythm problems and seizures.

Also known as: Persian Cyclamen, Sowbread · Cyclamen persicum

What makes it toxic

Cyclamine and related saponins, highest in the tuber. They irritate the gut and, in tuber-level doses, disrupt cardiac and neurological function.

Warning signs to watch for

Drooling, vomiting and diarrhea within hours; tuber ingestion can progress to a rapid or irregular heartbeat, tremors, seizures and collapse.

What to do if your dog eats it

Remove access and call your vet. Treat any dug-up or chewed tuber as an emergency and go to the clinic immediately rather than waiting for heart signs.

Common questions

My dog dug up a potted cyclamen and buried his nose in it — what now?

Assume tuber exposure. Call the vet or an ER right away with the amount chewed; early decontamination prevents the cardiac phase.

Are outdoor hardy cyclamen the same risk?

Yes. All Cyclamen species contain cyclamine, and garden corms are equally toxic when dug up by a dog.
