Bark Up the Wrong Tree

To pursue the wrong course of action or make a wrong assumption

Quick Definition

Bark up the wrong tree — to pursue the wrong course of action; to make an incorrect assumption about a person or situation. You are looking in the wrong place or blaming the wrong person.

Origin & History

The idiom comes from 19th-century American hunting. Hunting dogs would chase animals up trees and bark at them. If the quarry escaped to a different tree while the dog continued barking at the first one, the dog was literally barking up the wrong tree. The earliest figurative uses in print date from the early 1800s.

The phrase captures the idea of wasted effort caused by a wrong assumption — working hard but in entirely the wrong direction.
