Is Mother of Millions safe for dogs?

Yes, Mother of Millions (Kalanchoe tubiflora) is toxic to dogs. The plant contains cardiac glycosides — toxins that affect the heart muscle — and ingestion can cause vomiting, lethargy, abdominal pain, and potentially dangerous cardiac arrhythmias.

The most common signs are vomiting, diarrhea, and drooling, which typically begin within a few hours of ingestion. With larger ingestions, more serious symptoms can develop, including weakness, collapse, or an abnormal heart rhythm.

Do not induce vomiting and do not give any over-the-counter human medications. Call your vet or the ASPCA Animal Poison Control Center at (888) 426-4435 immediately. Call the same day for vomiting that won't stop, and call right away if your dog appears weak, collapses, or you saw him eat more than a mouthful.

Mother of Millions contains cardiac glycosides, a class of compounds that interfere directly with heart muscle function. This is the same mechanism that makes related Kalanchoe species medically significant — even a moderate ingestion can progress from gastrointestinal upset to cardiac arrhythmias, which is why prompt veterinary attention is recommended rather than a wait-and-see approach.
