Is Kalanchoe safe for Dogs?
✓ Sources checked by the Eaoae Safety Review · 2026-10-28 · Based on 3 sources
No, kalanchoe is unsafe for dogs. It contains bufadienolides -- cardiac glycosides that cause vomiting, diarrhea, weakness, abnormal heart rhythms, and possible cardiovascular collapse.
🚨 Emergency: Yes — contact your veterinarian immediately.
💡 Why
Kalanchoe (including mother-in-law plant and chandelier plant) is an extremely common houseplant, which is why it appears in poisoning statistics far out of proportion to its fame. Its bufadienolide toxins attack the heart: after initial vomiting and diarrhea, dogs may develop arrhythmias, profound weakness, and collapse. While many cases are mild GI upset, the cardiac risk makes every ingestion worth a vet call.
🩺 What to do
- Move kalanchoe plants out of your dog's reach or remove them.
- If chewing is suspected, call your vet -- mention possible cardiac effects.
- Monitor for vomiting and unusual tiredness.
❓ Common questions
Which part is most toxic?
The bufadienolides are concentrated in the flowers, but all parts -- leaves, stems, flowers -- contain the toxins.
What are the symptoms?
Vomiting, diarrhea, and lethargy within hours; severe cases add irregular heartbeat, weakness, and collapse.
My dog only chewed a leaf -- vet or not?
Keep kalanchoe plants out of reach or rehome them; curious dogs often chew fallen leaves.
