Is White-Leaved Rock Rose toxic to dogs?

Mildly. The ASPCA lists white-leaved rock rose 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. Cistus albidus is not listed on the ASPCA Toxic and Non-Toxic Plant database, and no specific toxic principles have been documented in horticultural literature. However, because the genus is not formally cleared by ASPCA, it is classified here as mildly-toxic as a precautionary measure. The plant produces a resinous sap that may cause mild skin irritation on contact.

Cistus albidus is not listed on the ASPCA Toxic and Non-Toxic Plant database, and no specific toxic principles have been documented in horticultural literature. However, because the genus is not formally cleared by ASPCA, it is classified here as mildly-toxic as a precautionary measure. The plant produces a resinous sap that may cause mild skin irritation on contact. Signs usually appear soon after chewing rather than hours later — watch for drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy after your dog has had access to white-leaved rock rose.

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.

The ASPCA classification Growli uses applies to both cats and dogs: White-Leaved Rock Rose is mildly toxic to cats as well. See the full white-leaved rock rose pet-safety guide for both species.
