Barking up the wrong tree
English Idiom
Meaning: To pursue a mistaken or misguided course of action. It's like focusing your energy or efforts on the wrong thing or misunderstanding the root cause of a problem.
Origin: The idiom 'Barking up the wrong tree' originates from early 19th century America, where hunting with dogs was common. Sometimes, dogs would mistakenly bark at the base of a tree, believing their prey was up there, when in fact, the animal had escaped to another tree. This led to the expression being used for any mistaken pursuit or false assumption.
