Barking up the wrong tree

Barking up the wrong tree is an idiomatic expression in English, which is used to suggest a mistaken emphasis in a specific context. The phrase is an allusion to the mistake made by dogs when they believe they have chased a prey up a tree, but the game may have escaped by leaping from one tree to another. The phrase means to mistake one's object, or to pursue the wrong course to obtain it.

In other words, "if you are barking up the wrong tree, it means that you have completely misunderstood something or are totally wrong."

Barking up the wrong tree became common use in nineteenth century America in reference to hunting raccoons with a hunting dog. When the nocturnal animal takes to a tree, the dog is supposed to remain at the base of the tree until its master arrives. However, in the dark, if the dog mistakes the tree where the raccoon has taken refuge, the hunter may lose it. The expression was commonly used by writers of western life and tales, appearing in works by James Hall, David Crockett, and Albert Pike.
