Is Lawson Cypress toxic to dogs?

Chamaecyparis lawsoniana

Mildly toxic to dogs

Mildly. The ASPCA lists lawson 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 lawsoniana is not individually listed by ASPCA but the genus contains essential oils (notably sabinene and other monoterpenes) that can cause gastrointestinal irritation if foliage is ingested by pets. Exercise caution with dogs and cats that chew vegetation.

What to do if your dog ate lawson cypress

  4. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice.
