My dog ate Winter Aconite — what to do

Step by step

  1. Take winter aconite away and remove any plant material from your dog's mouth so they cannot eat more.
  2. Note roughly how much was eaten and when — this helps the vet judge the risk.
  3. Do NOT induce vomiting unless a vet or poison-control specialist tells you to.
  4. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 (a consultation fee may apply) and follow their advice.
  5. Watch for drooling, pawing at the mouth, vomiting, loss of appetite, or lethargy, and bring a leaf or photo to the appointment.

This is general guidance, not veterinary advice. Pets vary, and a reaction may be to soil, fertiliser, or pesticide as well as the plant. When in doubt, call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435.

My dog ate winter aconite — FAQ

Is winter aconite poisonous to dogs?

Yes — the ASPCA lists Winter Aconite (Eranthis hyemalis) as toxic to dogs. All parts of Eranthis hyemalis are toxic to cats, dogs, and other animals. The plant contains cardiac glycosides (eranthin A and eranthin B, bufadienolide group) as well as protoanemonin, a skin and mucous-membrane irritant common in Ranunculaceae. Ingestion causes nausea, vomiting, abdominal pain, bradycardia, dyspnoea, and in severe cases cardiac arrest. A documented case records fatal pulmonary oedema in a dog. The bitter taste deters most casual nibbling but veterinary advice should be sought immediately if ingestion is suspected.

How serious is it if my dog ate winter aconite?

Winter Aconite is toxic to dogs and reactions can be significant, so treat any ingestion as urgent. Call your vet or poison control on (888) 426-4435 straight away rather than waiting to see if symptoms develop.

What symptoms should I watch for?

Signs usually appear soon after chewing: drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy. All parts of Eranthis hyemalis are toxic to cats, dogs, and other animals. The plant contains cardiac glycosides (eranthin A and eranthin B, bufadienolide group) as well as protoanemonin, a skin and mucous-membrane irritant common in Ranunculaceae. Ingestion causes nausea, vomiting, abdominal pain, bradycardia, dyspnoea, and in severe cases cardiac arrest. A documented case records fatal pulmonary oedema in a dog. The bitter taste deters most casual nibbling but veterinary advice should be sought immediately if ingestion is suspected. Any worsening or persistent symptoms warrant an immediate vet visit.

Should I make my dog vomit?

No — do not induce vomiting unless a vet or the ASPCA Animal Poison Control Center specifically tells you to. The wrong action can make things worse. Call (888) 426-4435 and follow professional advice.

How do I stop this happening again?

Keep winter aconite well out of reach, or swap it for an ASPCA non-toxic plant — see the best dogs-safe plants list.
