? about Line Breeding

What about evolution, if my grandpa had 100 hot nose dogs never outcrossed ever and pushed them to cold trail, my daddy did the same thing, i did also then my son did. would anyone say the dogs would never get better nosed than the first dogs my grandpa started with, I cant buy into that at all. some will say well they might learn to use there nose better thats all, or i would just be line breeding the better nosed dogs and it would just show up that way, i dont beleave that either. I don't think it takes 1000's of years either. In a given pack of any wild animal it takes only a few generations to alter there natural make up to adapt to there surroundings and I think dogs work the same way. Line breeding will be argued about until Jesus comes back, but if you dont work what ever dogs you have to there full ability then it doesnt really matter cause you will never know what you had anyway. I don't think most guys need to be breeders, myself included because it takes you spending alot of time, more than most of us really have, with your dogs watching them and working with them daily to really know what your working with, then you need to keep every pup until there atleast a year old, i think longer. then cull like hell and if you do that for 50 years your well on your way to being a breeder................................................ but JMO
