My thinking is that its half instinct and half reaction to ourselves.The way we react when seeing something or dare I say it ,thinking something ,has a large bearing on what my dogs will or wont chase .For those of you that stick to the same walking route ,try this .Think about turning a different way long before you get there and see what happens .Might just be me and my pack ?
When lamping and theres more than one quarry sat together ,think of one specific one and then slip the dog ?.
Done right ,the bond between human and dog is stronger than any other .
