Is Dieffenbachia (dumb cane) toxic to dogs & cats?
Also known as: dumb cane / leopard lily
🚑 What to do right after ingestion
Rinse the mouth, offer milk/ice water; emergency if breathing is affected.
Toxicity notes
Calcium oxalate plus soluble toxins double the insult — chewing causes intense oral pain and swelling, sometimes airway edema (hence the folk name dumb cane).
Poisoning symptoms
- • Heavy drooling
- • Swollen painful mouth
- • Vomiting
- • Voice changes
- • Trouble swallowing
Symptoms can be delayed (e.g. onion/garlic-induced hemolysis may take days) — a pet looking fine right now is no reason to relax.
FAQ
How much causes poisoning?
Calcium oxalate plus soluble toxins double the insult — chewing causes intense oral pain and swelling, sometimes airway edema (hence the folk name dumb cane).
Can I make my pet vomit at home?
Home-induced vomiting is not advised: corrosive cleaners, sharp bones or existing neurological signs make it dangerous, and improper technique risks aspiration pneumonia. Vomiting should be induced by a vet with proper drugs at the right moment — most effective within 1-2 hours. So “head to the clinic as soon as you know” beats “try to induce vomiting first”.
