Is Dark Green Ceratozamia toxic to dogs?

Yes — dark green ceratozamia is toxic to dogs according to the ASPCA. Keep it well away from any dog that chews plants; reactions can be significant. All Ceratozamia species are cycads in the family Zamiaceae and contain cycasin and related neurotoxins that cause liver failure and can be fatal to dogs, cats, and horses. The ASPCA lists cycads as toxic to pets. Seeds and cones contain the highest toxin concentration, but all parts including leaves, stem, and roots are hazardous. Seek emergency veterinary care immediately after any suspected ingestion.

Seek emergency veterinary care immediately after any suspected ingestion. 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 dark green ceratozamia.

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: Dark Green Ceratozamia is toxic to cats as well. See the full dark green ceratozamia pet-safety guide for both species.
