Is Stinking Trillium toxic to dogs?
Trillium foetidissimum
Mildly. The ASPCA lists stinking trillium 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. Trillium foetidissimum is not individually listed by the ASPCA on its Toxic or Non-Toxic Plant database. As with other Trillium species, roots and berries are the parts of greatest concern and likely contain steroidal saponins that can cause gastrointestinal irritation (nausea, vomiting, diarrhoea) in pets and humans if ingested. The strong scent may deter animal ingestion but should not be relied upon as a safety mechanism. Contact ASPCA Animal Poison Control (888-426-4435 in the US, or Animal PoisonLine on 01202 509 000 in the UK) or a vet promptly if ingestion occurs.
