If you follow the Higgins Method you have heard, or in his writings Brad mention the Circle of Death strategy. If you never heard or seen it happen then here is a video of Kepa and Ekahi demonstrating this strategy on Valley Quail.
The pack doing the circle of death, this is the same strategy (surrounding the prey) that Wolves, Coyotes, Wild Dogs in Africa ,and Lions use when hunting in a pack. Most hunters don’t even know that a gun dog will do these things on their own if you just leave them alone and trust the pack. Dogs are born knowing this, no training is necessary, but most people will not let the dog show what they really can do naturally without any human input due to a very high majority of hunters believe in obedience not trust.
