Barking Up The Wrong Tree

At times, specific breeds of dogs are used when hunting animals. Once a dog finds another animal, a chase ensues, and the fleeing animal will tend to utilize the nearby trees as a means of escape. Since most dogs are not capable tree climbers, they are content with remaining at the base of the tree and barking repeatedly to indicate to their owner where the terrified animal has gone.

Dogs are not perfect, so they can often times mistake what particular tree the animal fled to, and thus, as the saying goes, the dog is barking up the wrong tree.
