Is Three-lobed Coneflower toxic to dogs?

Rudbeckia triloba

Mildly toxic to dogs

Mildly. The ASPCA lists three-lobed coneflower 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. Rudbeckia triloba is not individually listed on the ASPCA toxic or non-toxic plant database for cats, dogs, or horses; a pet-safe classification cannot be confirmed. As with other rudbeckias, sesquiterpene lactones in the leaf hairs and sap may cause contact dermatitis or mild gastrointestinal irritation if ingested. Consult a vet if a pet ingests a significant quantity.
