Is Wild Arum Toxic to Dogs?
Also known as: Cuckoo Pint, Lords-and-Ladies, Arum maculatum · Arum maculatum
What makes it toxic
Insoluble calcium oxalate raphides concentrated in berries and tuber. The needle crystals pierce the lining of the mouth, tongue and throat on contact.
Warning signs to watch for
Sudden drooling, oral pain, pawing at the muzzle, vomiting and refusal to eat. Severe throat swelling is uncommon but possible after chewing berries.
What to do if your dog eats it
Flush the mouth with water and let the dog drink. Call your vet if symptoms last beyond a couple of hours or if swelling affects swallowing or breathing.
Common questions
My dog ate berries from a woodland arum plant — what should I do?
Expect strong mouth pain and drooling for a few hours. Rinse the mouth, offer water, and call the vet if vomiting persists or the airway sounds obstructed.
Is wild arum more dangerous than anthurium or peace lily?
They share the same oxalate mechanism and a broadly similar outcome — painful irritation, rarely a true emergency.
