Barking up the wrong tree

Using the slang term “barking up the wrong tree” means to pursue the wrong course of action or direct your efforts towards the wrong person or thing.

This phrase originates from the image of a dog barking at a tree to try and catch a squirrel, but the squirrel is actually in a different tree. It is often used to convey the idea that someone is blaming or accusing the wrong person for something or looking for answers or solutions in the wrong place.

Example 1:

Person A: “I heard someone broke into the house last night. I think it was the new neighbors.”
Person B: “I think you’re barking up the wrong tree. The new neighbors were out of town during that time.”

Example 2:

Friend A: “I can’t find my phone anywhere. I think you took it.”
Friend B: “You’re definitely barking up the wrong tree. I haven’t even seen your phone today.”
