Is Western Arborvitae Zebrina toxic to dogs?

Thuja plicata 'Zebrina'

Mildly toxic to dogs

Mildly. The ASPCA lists western arborvitae zebrina 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. Thuja 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 foliage contains volatile oils including thujone and ingestion may cause mild gastrointestinal upset (drooling, vomiting, diarrhoea) in dogs and cats.
