Is Greater Sea Kale toxic to dogs?

Mildly. The ASPCA lists greater sea kale 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. No known hazards or toxic principles are documented for Crambe cordifolia; the plant is in the edible Brassicaceae family and young leaves are consumed by humans. However, Crambe is not listed on the ASPCA Toxic and Non-Toxic Plant database, so an explicit pet-safe classification cannot be confirmed. Err on the side of caution and prevent pets from ingesting large quantities.

Err on the side of caution and prevent pets from ingesting large quantities. 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 greater sea kale.

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: Greater Sea Kale is mildly toxic to cats as well. See the full greater sea kale pet-safety guide for both species.
