What Are Peace Lilies?
Peace lilies (Spathiphyllum) are popular houseplants known for their elegant white blooms and air-purifying qualities. They thrive in low-light conditions, making them a common choice for indoor decoration. Despite their beauty, peace lilies contain calcium oxalate crystals, which can be harmful to pets if ingested.
Are Peace Lilies Poisonous to Dogs?

- Excessive drooling
- Pawing at the mouth
- Vomiting
- Difficulty swallowing
- Swelling of the tongue and lips
Although peace lilies are not fatal in most cases, their ingestion can cause significant discomfort and should be addressed promptly.

Rinse the Mouth: Use clean water to flush out any remaining plant particles from your dog’s mouth.

When to Call a Vet
If your dog eats a peace lily, monitoring their symptoms is crucial. While mild cases may only cause temporary discomfort, you should contact a veterinarian if your dog experiences severe swelling of the mouth, tongue, or throat, as this could lead to breathing difficulties. Persistent vomiting, excessive drooling, or trouble swallowing are also signs that medical attention is needed. Additionally, if your dog shows signs of distress, such as whining, pawing at the mouth, or unusual lethargy, it’s best to seek veterinary care. Although peace lily poisoning is rarely fatal, a vet can provide the necessary treatment to prevent complications and ensure your dog’s well-being.
