Is Blue Star Water Lily toxic to dogs?

Mildly. The ASPCA lists blue star water lily as mildly toxic to dogs — a chewing dog typically gets mouth irritation, drooling, and vomiting rather than a medical emergency, but it is still best kept out of reach. The ASPCA lists Nymphaea odorata as non-toxic to cats and dogs, but water lily leaves and rhizomes can cause mild vomiting or diarrhoea if consumed in quantity. Classified mildly-toxic as a precaution; contact your vet if a pet ingests significant plant material.

The ASPCA lists Nymphaea odorata as non-toxic to cats and dogs, but water lily leaves and rhizomes can cause mild vomiting or diarrhoea if consumed in quantity. Classified mildly-toxic as a precaution; contact your vet if a pet ingests significant plant material. Signs usually appear soon after chewing rather than hours later — watch for drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy after your dog has had access to blue star water lily.

Stay calm. Remove any plant from your dog's mouth and take the plant away. Note how much was eaten and when, and do not induce vomiting unless told to. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice; a leaf or photo helps the vet treat it correctly.

The ASPCA classification Growli uses applies to both cats and dogs: Blue Star Water Lily is mildly toxic to cats as well. See the full blue star water lily pet-safety guide for both species.
