Is Giant Dioon toxic to dogs?

Dioon spinulosum

Toxic to dogs

Yes — giant 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 spinulosum contains cycasin (methylazoxymethanol glucoside), the potent hepatotoxic compound present throughout the Zamiaceae family including Cycas revoluta (sago palm), which the ASPCA lists as toxic to cats and dogs. All parts — seeds, leaves, and roots — are toxic; seeds contain the highest concentrations. Ingestion causes vomiting, bloody diarrhoea, liver failure, and is potentially fatal. Seek immediate emergency veterinary care if ingestion is suspected.

What to do if your dog ate giant dioon

  1. Remove any plant material from your dog's mouth and move giant 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.
  5. Bring a leaf or photo of giant dioon to the appointment so it can be treated correctly.
