What does it mean "Barking up on the Wrong Tree"

I got you covered, Jose!

"Barking up the wrong tree" connotes making the wrong choice, asking the wrong person, or doing the wrong course of action. 

Let’s try using it in different situations. Firstly, we can say, “I think I barked at the wrong tree when I chose this red shirt for my colleague's wedding. It is too eye-catching.” 

Secondly, “You’re barking at the wrong tree for asking me who ate the last slice of pie. I haven’t been out of my room all day.” 

Lastly, “Your mom didn’t know that she was barking at the wrong tree as she continuously used her car keys to open the door to our house earlier.”
