Without putting too fine a point on it you?re losing control over this dog and if you allow it to keep doing what he?s doing it won?t be long before he legs it here, there and everywhere whenever he wants to.
Nip this problem in the bud by walking your dog tight at heel and insist his neck and shoulder stays level with your knee; if you carry the gun on your right arm he should walk on your left side and vice versa if the gun is over your left forearm.
As soon as he starts to pull ahead ? or lower his head ? give a stern ?heel? command, at the same time tapping your thigh to indicate where you want him.
If he continues to do it, reach down and give his ear and quick tweak followed by the ?heel? command.
