Etymology

A simile derived from the behavior of hunting dogs (such as pointers or setters) trained to track and “point” to game birds. These dogs are noted for their high energy, keen instincts, and refusal to abandon a scent until the objective is secured.

Usage

Context: Used to describe someone who is not merely “busy” with general tasks, but is hyper-focused on a single target. It often implies a level of obsession or a refusal to rest until the “quarry” is caught.

In a sentence: Ever since he heard about that promotion, he’s been busy as a bird dog trying to close the deal.
