Is Broad-leaf Horncone toxic to dogs?

Ceratozamia latifolia

Toxic to dogs

Yes — broad-leaf horncone is toxic to dogs according to the ASPCA. Keep it well away from any dog that chews plants; reactions can be significant. This classification follows the ASPCA Toxic and Non-Toxic Plant List. All parts of Ceratozamia latifolia contain cycasin (a potent hepatotoxin) and the neurotoxin BMAA, consistent with all Zamiaceae cycads. Ingestion by dogs or cats causes vomiting, diarrhoea, acute liver failure, and potentially fatal neurological effects. ASPCA classifies cycads as severely toxic. Seeds pose the greatest risk. Keep entirely out of reach of pets and children.
