i define great dog work in several ways. i had a wire haired vizsla who would typically point his pheasants from respectable distances of usuallyIMHO you haven't seen great dogwork until you watch a pointing dog point-creep to reposition-point again - creep to reposition and this goes on numerous times. A dog that can reposition itself and not over pressure a bird is fantastic. Dogs only get that way with experience and unfortunately most never get enough.
My buddy had a absolutely fabulous gsp that had worked thousands of wild birds. We chased that dog across a pasture on a point creep point for a 100 yards short of a mile. Another friend had driven around and was parked on the road. The bird flushed when he slammed the door of the jeep. Bird flew right across in front of him and he dropped it.
I believe if the guy and vehicle hadn't arrived we would have got that bird when it stopped in the heavier cover of the ditch.
15-25 yards. In CRP the birds would typically run and stop, run and stop. he would hold point until i released him to relocate the bird, point and relocate several times, until finally when released he would run 50-75 yards in a straight line following the general direction of the bird, stop and hunt back to me where I stood and watched him lock down on his bird, numerous times. His natural instincts took over as he trapped the bird between him and me, as I would walk in and flush the bird sitting on the dogs nose. A thing of beauty.
That's something you would be hard pressed to teach a dog to do, I give him all the credit.
