I believe that if you want a show dog that works you have to breed for the working aspects first. I firmly believe in form follows function. But you have to also look at the big time show rings and differences in show dogs and working dogs. Look at Labs and Collies for example. Show Labs and Collies are larger and not as athletic looking than the field Labs and Collies. And to be honest those field Labs and Collies tend to not do as well in the show ring from what I've seen because show people like the larger looking dogs.
