Is Caucasian Comfrey toxic to dogs?

Symphytum caucasicum

Mildly toxic to dogs

Mildly. The ASPCA lists caucasian comfrey 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. Symphytum species contain pyrrolizidine alkaloids (PAs), which are hepatotoxic if ingested in quantity. ASPCA does not individually list Symphytum caucasicum, but all Symphytum species are considered mildly to moderately toxic to dogs, cats, and horses due to PA content. The rough, bristly leaves also cause contact dermatitis in sensitive individuals. Keep pets away and wear gloves when handling.
