Toxic to dogs

Yes — narrow-leaf dioon 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. Dioon angustifolium, like all cycads (Zamiaceae), contains cycasin and macrozamin — potent hepatotoxins and neurotoxins.

Any ingestion warrants immediate emergency veterinary treatment.
