Frequently asked questions
- Are calla lilies poisonous to dogs?
- Yes. According to the ASPCA, calla lilies (Zantedeschia aethiopica) are toxic to dogs. All parts of the plant contain insoluble calcium oxalate crystals that release when the plant is chewed, causing immediate oral pain and irritation.
- What happens if my dog eats a calla lily?
- Chewing releases needle-like calcium oxalate crystals (raphides) that embed in the mouth and throat tissues, causing oral irritation, intense burning of the mouth, tongue and lips, excessive drooling, vomiting, and difficulty swallowing. Signs usually appear quickly after contact. Contact your veterinarian or the ASPCA Animal Poison Control Center at (888) 426-4435.
- Is the calla lily a true lily, and is it as dangerous as lilies that cause kidney failure?
- No. Despite the name, the calla lily is not a true lily (Lilium/Hemerocallis); it belongs to the Araceae family. It does not cause the acute kidney failure that true lilies cause in cats. Its toxicity comes from insoluble calcium oxalates, which typically cause painful but localized oral and gastrointestinal irritation rather than organ failure. Even so, ingestion warrants veterinary attention.
