Is Dieffenbachia Toxic to Dogs?
Also known as: Dumb Cane, Tropic Snow, Exotica, Spotted Dumb Cane · Dieffenbachia seguine
What makes it toxic
Insoluble calcium oxalate raphides plus a proteolytic enzyme in the sap. The crystals pierce the mucous membranes and the enzyme amplifies inflammation.
Warning signs to watch for
Sudden oral pain, drooling, lip swelling, retching, vomiting and refusal to eat. Heavy stem chewing can cause enough throat swelling to affect breathing.
What to do if your dog eats it
Flush the mouth with water, remove plant debris and offer water or ice to drink. Call your vet; go immediately if the tongue or throat looks swollen or breathing is noisy.
Common questions
How much dieffenbachia hurts a dog?
Even a few bites cause real oral pain. Serious systemic poisoning is uncommon — the danger is local tissue swelling, not organ damage.
Should I make my dog vomit after chewing dieffenbachia?
No. Inducing vomiting adds more crystal injury to the throat. Let a vet handle decontamination if the exposure was large.
Is it safe to keep if the dog ignores it?
Dogs are unpredictable chewers, and this plant punishes chewing. Put it well out of reach or pick a safer species.
