Yes, kalanchoe is toxic to dogs. Chewing flowers or leaves delivers cardiac glycosides — GI upset first, heart effects in bigger doses.

Also known as: Flaming Katy, Christmas Kalanchoe, Widow’s Thrill, Mother of Millions relative · Kalanchoe blossfeldiana

What makes it toxic

Bufadienolide cardiac glycosides in all tissues, highest in the flowers. They interfere with cardiac conduction the way digitalis does.

Warning signs to watch for

Drooling, vomiting and diarrhea within hours; severe cases show weakness, bradycardia, arrhythmias and collapse.

What to do if your dog eats it

Take material away, note quantity eaten and call your vet. Heart changes or collapse means ER immediately — ECG monitoring and supportive care save severe cases.

Common questions

How dangerous is one kalanchoe flower head?

Flowers are the most concentrated part, so a whole head eaten by a small dog is worth a same-day vet call, not just monitoring.

Why do gift kalanchoes keep poisoning pets?

They bloom for months indoors at pet height. If you receive one, give it to a pet-free home or place it firmly out of reach.
