Is Ceanothus 'Concha' toxic to dogs?

Mildly. The ASPCA lists ceanothus 'concha' 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. Ceanothus (California lilac) is not individually listed on the ASPCA's toxic or non-toxic plant database, so its status for cats and dogs is unconfirmed; it is not the same as true lilac (Syringa). Treat with caution, discourage chewing, and consult a vet if ingested. Do not assume it is pet-safe.

Treat with caution, discourage chewing, and consult a vet if ingested. Do not assume it is pet-safe. 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 ceanothus 'concha'.

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: Ceanothus 'Concha' is mildly toxic to cats as well. See the full ceanothus 'concha' pet-safety guide for both species.
