Is Narrow-leaved Water Plantain toxic to dogs?

Alisma lanceolatum

Mildly toxic to dogs

Mildly. The ASPCA lists narrow-leaved water plantain 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. Alisma lanceolatum is not individually listed by the ASPCA. However, Alisma species contain acrid, irritant compounds (alisols and proto-anemonin-like substances) that can cause oral and gastrointestinal irritation if ingested raw. These substances are partly broken down on drying. As the ASPCA listing is absent and irritant compounds are documented in the genus, it is classified as mildly-toxic as a precaution. Keep pets away from the foliage and roots.
