Is Giant Water Lily toxic to dogs?

Nymphaea gigantea

Mildly toxic to dogs

Mildly. The ASPCA lists giant 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. This classification follows the ASPCA Toxic and Non-Toxic Plant List. Nymphaea gigantea is not specifically listed by the ASPCA; however, some Nymphaea species contain alkaloids (nupharamine alkaloids) in rhizomes that may cause gastrointestinal upset if ingested in quantity. Classified as mildly-toxic as a precaution; not expected to cause serious harm in brief contact but keep pets from chewing rhizomes.
