The test of time and generations, is what proves a "true" dogman. I have had the pleasure of being well acquainted with a few in more than one breed. They all started with some good solid blood and in time more or less made it their own producing generations of good dogs. They didn't scrap what they had every year or two and have to start over but continued on with good success maintaining the base they had. Their stock was well sought after and respected by most others that knew what a good dog was. My compliments to those men as that is no easy task and not everyone that comes down the pike can achieve it.
Cant put it no better than that...
