SORRY is this for real, are we talking about the little yappy black and tan things. crossed with a whippet or grey hound. what would the point of that be, what quality,s would that bring,that you couldnt get from a "working" terrier. As for crufts that show is were every body who shows wants to go. so you breed to the k c standard of course the show has f***ed up breeds. i know people that show whippets, they are not allowed to run because this would muscle them up and wreck there movement, not allowed to get muddy either this wrecks there coat. These dogs do well at shows. Good luck with the
