Verified against ASPCA/provenance audit 2026-05-06 on May 6, 2026.
Signs to watch for
Vomiting, diarrhea, lethargy, and potential cardiac arrhythmias.
Escalation note
The toxins in this plant can affect the heart muscle. Seek veterinary attention promptly if ingestion is observed or suspected.
First aid at home
Call ASPCA Animal Poison Control at (888) 426-4435 or your veterinarian as soon as possible. Do not induce vomiting unless a veterinarian instructs you to.
What to watch for
Vomiting and diarrhea are by far the most common signs — that's what nearly every dog shows. Watch additionally for lethargy, weakness, or collapse, and any sign of an irregular heartbeat (panting at rest, sudden weakness). Cardiac signs are uncommon but most likely with large ingestions.
Time window
Onset and duration are not well documented; ASPCA states ingestion most often results in GI irritation, with cardiac changes seen mainly with larger ingestions.
When to call the vet
Call your veterinarian or ASPCA Animal Poison Control (888-426-4435) any time vomiting starts after exposure. Call immediately — don't wait — if your dog ate a large amount, seems weak or wobbly, or you notice an unusually fast or irregular heartbeat.
What this means for your dog
Dogs that chew kalanchoe usually end up vomiting; the bigger concern is the bufadienolides — cardiac glycosides that, in larger ingestions, can affect heart rate and rhythm. Most cases stay GI, but the cardiac risk is real and worth a phone call.
