Is Poplar-Leaved Rock Rose toxic to dogs?

Mildly. The ASPCA lists poplar-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 populifolius is not listed on the ASPCA Toxic and Non-Toxic Plants database; no specific toxic compound has been confirmed for this species in veterinary literature. As explicit non-toxic confirmation is absent, a precautionary mildly-toxic classification is applied; seek veterinary advice if pets consume the foliage.

As explicit non-toxic confirmation is absent, a precautionary mildly-toxic classification is applied; seek veterinary advice if pets consume the foliage. 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 poplar-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: Poplar-Leaved Rock Rose is mildly toxic to cats as well. See the full poplar-leaved rock rose pet-safety guide for both species.
