Is Tomaselli's Dioon toxic to dogs?

Dioon tomasellii

Toxic to dogs

Yes — tomaselli's 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. Like all members of Zamiaceae, Dioon tomasellii contains cycasin and BMAA neurotoxin throughout all plant parts. Ingestion causes severe vomiting, acute liver failure, neurological damage, and can be fatal to dogs and cats. Seeds are especially dangerous. ASPCA lists cycads as severely toxic; Dioon carries the same toxin profile as the well-studied sago palm.

What to do if your dog ate tomaselli's dioon

  1. Remove any plant material from your dog's mouth and move tomaselli's dioon out of reach.
  2. Note how much was eaten and when, and watch for drooling, vomiting, or lethargy.
  3. Do not induce vomiting unless a vet or poison-control specialist instructs you to.
  4. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice.
