Is Boulevard Cypress toxic to dogs?

Chamaecyparis pisifera 'Boulevard'

Mildly toxic to dogs

Mildly. The ASPCA lists boulevard cypress 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. Chamaecyparis is not individually listed on the ASPCA toxic or non-toxic plant lists, so a pet-safe label cannot be confirmed; treat with caution and verify with a vet. The aromatic foliage contains volatile oils and ingestion may cause mild gastrointestinal upset (drooling, vomiting, diarrhoea) in dogs and cats.
