Is Comb Cycad toxic to dogs?

Yes — comb cycad is toxic to dogs according to the ASPCA. Keep it well away from any dog that chews plants; reactions can be significant. Cycas pectinata, like all members of the Cycas genus, contains cycasin (methylazoxymethanol), a potent hepatotoxin. Seeds are particularly concentrated with the toxin. The ASPCA lists all cycads as toxic to dogs and cats; symptoms include vomiting, bloody stools, liver failure, and death. All parts — leaves, seeds, and roots — should be kept away from pets.

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 comb cycad.

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: Comb Cycad is toxic to cats as well. See the full comb cycad pet-safety guide for both species.
