What this means for your dog

Dogs — extremely toxic, treat as an emergency. ASPCA lists cycads (Cycas and Zamia, including sago palm) as toxic to dogs; cycasin and BMAA in every part of the plant — and especially the seeds — cause acute liver failure. Pet Poison Helpline notes that even a single seed can kill a dog.

What to watch for

Within hours: drooling, vomiting (often with blood), diarrhea, and loss of appetite. Over the next 1–3 days: jaundice, dark or tarry stools, easy bruising, increased thirst, weakness or wobbly gait, tremors, and seizures as the liver fails.

Time window

GI signs start 15 minutes to several hours after ingestion. Neurologic signs and liver failure typically appear within 2–3 days. Hospitalization usually runs at least 3–5 days.

When to call the vet

Call your vet or ASPCA Animal Poison Control (888-426-4435) immediately — every minute matters. Pet Poison Helpline reports roughly 50% mortality even with aggressive treatment, and survival depends on getting the dog decontaminated within the first hour or two.

First aid at home

Bring the dog and a sample or photo of the plant straight to the nearest emergency vet — do not wait for symptoms. Do not induce vomiting at home unless directly instructed by a vet or poison control, and do not give activated charcoal on your own. Call ASPCA Animal Poison Control (888-426-4435) or Pet Poison Helpline (855-764-7661) on the way.
