Protoanemonin, released from ranunculin when the leaves, stems or flowers are crushed. It irritates mucous membranes and the digestive tract.

Common questions

The taste is so acrid that most dogs quit immediately, causing only short-lived irritation. If he returns to chew repeatedly, fence off the plant or redirect with toys.

Is clematis worse for dogs than for humans?

Not meaningfully — it irritates both, and humans rarely eat it. Dogs are the practical risk case because they chew first and regret later.
