Is Sago Palm Toxic to Dogs?

The short version
- Sago Palm (Cycas revoluta) is listed as toxic to dogs, cats, and horses by the ASPCA Animal Poison Control Center; the toxic principle is cycasin.
- Every part is toxic and the seeds carry the most cycasin; clinical signs include vomiting, bloody stool, liver damage, liver failure, and death (ASPCA).
- Treat any ingestion as an emergency; liver effects can appear 24 to 72 hours later, so a dog that seems fine can still be in danger.
- Florida's native coontie (Zamia integrifolia) is also a cycad and also toxic per the ASPCA, so it is not the safe version.
- Dog-safe Florida swaps for the same fan-palm look include Dwarf Palmetto (Sabal minor) and Cabbage Palm (Sabal palmetto), neither on the ASPCA toxic list.
Quick answer
Yes, and it is one of the most dangerous plants a Florida dog owner can have in the yard. The Sago Palm (Cycas revoluta) is listed as toxic to dogs, cats, and horses by the ASPCA Animal Poison Control Center. Every part contains cycasin, and the seeds are the worst; ingestion can cause vomiting, bloody stool, liver failure, and death. If your dog ate any part of a sago, call the ASPCA Animal Poison Control Center at (888) 426-4435 or your emergency vet right now.
Sago palms are everywhere in Florida landscaping, from foundation plantings in Orlando subdivisions to container specimens on Tampa patios. They are not actually palms, and they are far more dangerous to dogs than their tidy look suggests. This is the one plant on this site that warrants an emergency-vet call on any known ingestion, not a wait-and-see.
What the ASPCA says
The ASPCA Animal Poison Control Center lists Sago Palm (Cycas revoluta, also sold as coontie palm, cardboard palm, and under the broader cycad and zamia names) as toxic to dogs, cats, and horses. The toxic principle is cycasin. Clinical signs include vomiting, melena (dark, bloody stool), increased thirst, hemorrhagic gastroenteritis, bruising, coagulopathy, liver damage, liver failure, and death.
The seeds carry the highest concentration of cycasin, and dogs are drawn to them. Published veterinary case series report survival rates well short of certain even with aggressive treatment, which is why this plant earns a different level of urgency than most of the toxic list.
How much sago palm is dangerous for a dog?
Treat any amount as an emergency. The ASPCA does not publish a safe dose, and a single seed has been enough to cause liver failure in a dog. Because liver damage can progress over 24 to 72 hours, a dog that seems fine an hour after eating a seed can still be in serious trouble the next day. Do not wait for symptoms. Call the ASPCA Animal Poison Control Center at (888) 426-4435 or head to an emergency vet the moment you know a sago was chewed.
Can a sago palm kill a dog?
Yes. Unlike many plants on the toxic list where the realistic outcome is stomach upset, sago palm poisoning frequently causes liver failure, and death is a documented outcome even with treatment. This is the plant most worth removing outright if you have a dog that mouths things in the yard, rather than relying on placement.
A note on coontie, Florida's native cycad
Florida has a native cycad, coontie (Zamia integrifolia, sometimes sold as Zamia pumila), and it is a genuinely valuable plant: it is the only host for the rare atala butterfly. But it is a cycad, and the ASPCA lists cycads and zamias as toxic to dogs alongside the sago. Coontie is a good ecological choice for a bed your dog never enters. It is a poor choice along a dog run. Do not treat the native cycad as the safe version.

| Plant | Dog Safe? | Notes |
|---|---|---|
| Sago Palm (Cycas revoluta) | No | Toxic to dogs, cats, and horses per the ASPCA; seeds cause liver failure |
| Coontie (Zamia integrifolia) | No | Native cycad and atala host, but the ASPCA lists cycads and zamias as toxic; treat the same |
| Dwarf Palmetto (Sabal minor) | Yes | Not on ASPCA toxic plant list; native fan palm, compact, takes shade and wet soil |
| Cabbage Palm (Sabal palmetto) | Yes | Not on ASPCA toxic plant list; Florida's state tree, true palm silhouette |
What to do if your dog ate sago palm
- Treat it as an emergency. Do not wait for symptoms.
- Call the ASPCA Animal Poison Control Center at (888) 426-4435 or go straight to an emergency vet.
- Bring a piece of the plant or a photo, and note whether seeds were involved.
- Do not induce vomiting unless a vet tells you to.
- Expect the vet to run liver bloodwork and monitor over several days; liver effects can appear late.
