An example of two different terrier men are my brother and me, he values a good bushing terrier the same way I value a good earth dog. Although you couldn't give a me a good bushing dog because it's not what I enjoy, but he loves it. He's the same the last thing he would want is to be digging a hole for a fox but I wouldn't want to doing anything else but digging to a terrier! Both terrier work, horse for courses I suppose
