Is Chestnut Dioon toxic to dogs?

Dioon edule

Toxic to dogs

Yes — chestnut 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 edule contains cycasin (methylazoxymethanol glucoside), the same hepatotoxic glycoside found in all Zamiaceae cycads including Cycas revoluta (sago palm), which the ASPCA lists as toxic to cats and dogs. Ingestion causes vomiting, bloody diarrhoea, liver necrosis, and can be fatal. Seeds are particularly high in toxin concentration. Emergency veterinary treatment is required for any suspected ingestion.

What to do if your dog ate chestnut dioon

  1. Remove any plant material from your dog's mouth and move chestnut 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 chestnut dioon to the appointment so it can be treated correctly.

General guidance, not veterinary advice. If you think your dog has eaten chestnut dioon, contact your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 — do not wait for symptoms to worsen.
