Not sure if it's been mentioned or not, bu I also believe that there is an art to breeding that has to work with the science. No matter what breeding scheme one chooses to employ...there has to be both. What factors in to the art? IMO, the two biggest factors are objectivity and the ability to sort. If you aren't objective, everything else is a moot point. As for the sort...if you don't have the knowledge and experience to know what your looking at, you have a hard row to hoe.
I totally agree...you have to know what a hog dog is...sometimes the very best dogs are very laid back until the tail gate drops...
It might sound something from way out in left field...but because I had so much time running the plant from a control room I would read cover to cover my monthly full cry...then I would study the world champion hound/cur pictures...looking at the pictures for what appeared to be common among the greats...there is a air to most of them that is hard to described...an above it all attitude...
