Yes, elephant ears are toxic to dogs. Every variety carries calcium oxalate crystals that injure the mouth, throat and stomach when chewed.

Also known as: Caladium, Angel Wings, Alocasia, Colocasia · Caladium bicolor

What makes it toxic

Insoluble calcium oxalate raphides throughout leaves, stems and tubers. On chewing they fire into the mucous membranes, causing chemical-plus-mechanical injury.

Warning signs to watch for

Drooling, oral swelling, vomiting, retching, pawing at the mouth and reluctance to eat. Large exposures can swell the throat enough to affect breathing.

What to do if your dog eats it

Flush the mouth with water, remove plant material and call your vet. Immediate clinic visit if breathing sounds abnormal or the tongue swells.

Is elephant ear poisoning fatal to dogs?
