He was barking up the wrong tree.
Naaaaagggghhhhhhh.
Someone who stays up at night wondering if there really is a dog.
Put your ear up to a tree and listen for the bark !
Hang onto your bark this will be no ordinary spark
Banned from the petting zoo, apparently.
He never got banned.
Bargain up the wrong tree !
A dog that keeps barking up the wrong tree !
