My dog ate Cardboard Palm - what should I do?
Zamia spp.
Potentially toxic
Contact your veterinarian or an animal poison-control resource now, especially if any amount was chewed or swallowed.
Verified against ASPCA/provenance audit 2026-05-06 on May 6, 2026.
Signs to watch for
Vomiting, bloody stool, abdominal pain, bruising, and liver damage.
Escalation note
The entire plant is toxic, with seeds being the most dangerous part. Seek emergency veterinary care immediately if your dog has chewed or eaten any part of this plant.
First aid at home
Call ASPCA Poison Control (888-426-4435) or an emergency vet right away. If it's safe, remove any plant material from your dog's mouth and bring a piece or clear photo of the plant for identification. Do not induce vomiting at home — that decision is for the veterinarian.
What to watch for
Expect vomiting (sometimes bloody) and dark, tarry stools early on. As the liver is hit, look for jaundice, easy bruising, nosebleeds, or unexplained bleeding. Severe cases progress to abdominal pain, weakness, ataxia, tremors, and seizures.
Time window
GI signs usually start within 15 minutes to a few hours of ingestion. Neurologic signs can appear at 4–12 hours, and clinical liver failure typically declares itself at 2–3 days, with bloodwork changes detectable at 24–48 hours.
When to call the vet
Call immediately — don't wait for symptoms. Roughly half of treated cases are still fatal, and the survival lever that matters most is how quickly the dog gets to a clinic for decontamination.
What this means for your dog
Dogs: this is an emergency. Cardboard palms (Zamia spp.) are close relatives of sago palms and share the same cycasin toxicity. ASPCA classifies the entire plant as toxic to dogs, with seeds carrying the highest dose — a single seed has been enough to cause acute liver failure.
