Dogs
ToxicEmergencyEvery part of the sago palm is toxic, especially the seeds, and ingestion can cause severe vomiting, liver failure, and can be fatal in dogs.
Cats
ToxicEmergencySago palm carries the same severe, potentially fatal liver-failure risk for cats.
A toxin that attacks the liver
Sago palms (also called cycads) contain cycasin and other toxins that damage the liver and can affect the stomach and nervous system. The seeds, often called nuts, are the most concentrated part, and dogs may be drawn to them.
Common in landscaping
Sago palms are popular ornamental plants in warm regions, including Southern California, and are also sold as houseplants. A seed that has fallen in the yard or a leaf chewed on a walk can be enough to cause serious illness.
Signs to watch for
- Vomiting, sometimes with blood
- Diarrhea and drooling
- Lethargy
- Later: yellowing of the skin or gums, bleeding, seizures
Illness can progress quickly, and survival depends heavily on how fast treatment starts.
What to do
This is a true emergency. Call your vet or poison control or go to an emergency clinic immediately, and bring a piece of the plant or a clear photo if you can.
Safer alternatives
If you want a palm for a home with pets, ask your nursery about pet-safe options and check them against the ASPCA's plant list.
Frequently asked questions
Is the whole plant poisonous?
Yes. All parts are toxic, with the seeds the most dangerous.
Can I keep a sago palm if my dog never chews plants?
The risk remains, especially from fallen seeds. Many owners choose to remove the plant or fence it off; talk to your vet about your situation.
