It,s really difficult to define ,Personally I don,t think it,s about how good thier dogs are ,or even how much tackle they get , I v met a couple of ,what I consider to be good dog men , over the years and the thing they had in common , was a presence , an aura , call it what you want ,but they had an affinity with thier dogs , a bond , a partnership , and I don,t mean just a well trained dog , but something stronger , as I said it,s really difficult to define , but there is a differance between , a man who likes his dogs and a good dog man .
