Are willow trees poisonous to dogs?
—Tim Dear Tim, The bark of the Corkscrew Willow (Salix matsudana) and many other willow trees contains salicylates, which are similar to aspirin. Salicylate poisoning is possible if the tree is ingested in large amounts. Dogs can be affected as well as cats, but cats are particularly vulnerable because they do not metabolize salicylates well. Thus, the ASPCA recommends discouraging your pet from chewing on willow trees.
