Safety status
What this means for your dog
Dogs: this is an ER visit, not a wait-and-see. Cardboard cycad contains cycasin (and macrozamin), which target the liver, and as little as one or two seeds has killed dogs. Even with aggressive treatment, roughly half of cases are still fatal — outcomes hinge on how fast decontamination starts.
What to watch for
Vomiting (sometimes bloody) and dark or tarry stools usually come first. As the liver is hit, look for jaundice, easy bruising, nosebleeds, or unexplained bleeding. Severe cases progress to weakness, ataxia, tremors, seizures, or collapse.
Time window
GI signs typically appear within 15 minutes to several hours. Neurologic signs (ataxia, tremors, seizures) can develop at 4–12 hours, and acute liver failure usually declares itself at 2–3 days, with bloodwork changes detectable at 24–48 hours.
When to call the vet
Call right now, on suspicion alone. Don't wait for vomiting to start and don't wait to see how the dog looks at home — early induced vomiting at the clinic is the single biggest survival lever.
First aid at home
Call ASPCA Poison Control (888-426-4435) or an emergency vet immediately. 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's for the veterinarian to decide.
