Frequently asked questions
- Are peace lilies poisonous to dogs?
- Yes. According to the ASPCA, peace lilies (Spathiphyllum) are toxic to dogs. They contain insoluble calcium oxalate crystals that are released when a dog chews the plant, causing immediate oral pain and irritation.
- What happens if my dog eats a peace lily?
- Chewing releases sharp insoluble calcium oxalate crystals, which cause oral irritation, intense burning of the mouth, tongue and lips, excessive drooling, vomiting, and difficulty swallowing. Signs usually appear quickly. Most cases are mild because the painful burning typically stops the dog from eating much, but contact your veterinarian or ASPCA Poison Control at (888) 426-4435.
- Is a peace lily as dangerous as a true lily for pets?
- No. Despite the name, the peace lily is not a true lily (it is in the Araceae family, not Liliaceae). It does not cause the life-threatening kidney failure that true lilies (Lilium and Hemerocallis) cause in cats. The peace lily's calcium oxalate toxicity is painful but generally not life-threatening, though severe mouth swelling can rarely affect breathing.
