Whoa has not always been an important part of training, but a quick historical peek at how bird dogs developed helps give it perspective. As far back as the 16th century, we as hunters have been teaching dogs to whoa to signal the presence of game. Dogs were trained to circle, point, or circle and point game. For dogs required to hold point they were taught whoa. Dogs had to be well trained as hunters used crossbows prior to the invention of the shotgun.
