Is Prickly Cycad toxic to dogs?

Encephalartos altensteinii

Toxic to dogs

Yes — prickly cycad 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 Encephalartos altensteinii contain cycasin (methylazoxymethanol glucoside), a potent hepatotoxin. Ingestion by cats or dogs causes vomiting, diarrhoea, liver failure, and potentially death. Encephalartos is in the family Zamiaceae and shares the same toxic profile as Cycas (sago palm), which the ASPCA lists as toxic. Seek emergency veterinary care immediately if ingestion is suspected.

What to do if your dog ate prickly cycad

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