Frequently asked questions
- Are Elephant Ears poisonous to dogs?
- Yes. The ASPCA lists Elephant Ears (Colocasia esculenta) as toxic to dogs. All parts of the plant contain insoluble calcium oxalate crystals, which cause intense oral irritation when chewed or swallowed.
- What happens if my dog chews on an Elephant Ear plant?
- The insoluble calcium oxalate crystals embed in the tissues of the mouth, causing immediate burning, pain and swelling of the mouth, tongue and lips, excessive drooling, vomiting, and difficulty swallowing. In severe cases, swelling of the airway can occur, which is an emergency — especially in small dogs.
- Which part of the Elephant Ear plant is toxic to dogs?
- All parts of the plant are toxic, including the leaves, stems, and tubers, because the insoluble calcium oxalate crystals are present throughout. There is no safe portion to allow a dog to eat.
