Is Brunnera macrophylla 'Looking Glass' toxic to dogs?

Mildly. The ASPCA lists brunnera macrophylla 'looking glass' 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. Brunnera macrophylla is not individually listed in the ASPCA Toxic/Non-Toxic Plants database, so its status is unconfirmed. As a borage-family (Boraginaceae) plant it may contain low levels of pyrrolizidine alkaloids. Treat with caution and verify with a vet if ingested; do not assume it is pet-safe.

Stay calm. Remove any plant from your dog's mouth and take the plant away. Note how much was eaten and when, and do not induce vomiting unless told to. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice; a leaf or photo helps the vet treat it correctly.
