Well going to throw my two cents in the mix. I raised and schooled Gr Ch Titere. He was the only one out of the litter that wasn't single minded. He would use your style against you till he got his way and then it was just a matter of time. Remember you aren't out to impress but to get that win. And the stiffer the competition the harder it is to get your way. I do believe you can breed your animals to have a specific style. I have three generations of dogs on the ground off Panthro Jr. who was the best producer of that litter and all have smarts but are back end monsters. To really key on that specific trait you must have animals that pass the trait along on constantly and be fairly tightly bred.
