Is Amorphophallus muelleri toxic to dogs?

Yes — amorphophallus muelleri is toxic to dogs according to the ASPCA. Keep it well away from any dog that chews plants; reactions can be significant. Not individually listed by the ASPCA, but as an Araceae aroid the corm and foliage contain abundant insoluble calcium oxalate raphides — confirmed in porang flour research as a high-oxalate hazard requiring processing to remove. In pets, chewing causes oral pain, drooling, vomiting and swallowing difficulty. The raw tuber is also unsafe for humans until properly leached and cooked. Treat as toxic.

In pets, chewing causes oral pain, drooling, vomiting and swallowing difficulty. The raw tuber is also unsafe for humans until properly leached and cooked. Treat as toxic. Signs usually appear soon after chewing rather than hours later — watch for drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy after your dog has had access to amorphophallus muelleri.

Stay calm. Remove any plant from your dog's mouth and take the plant away. Note how much was eaten and when, and do not induce vomiting unless told to. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice; a leaf or photo helps the vet treat it correctly.
