if your looking for a line of dogs that do this generation after generation you would be best to look at the plott dogs . our curs as a rule were bred for close to mid range dogs for gens, not that there aren't some curs that will go but they don't consistantly produce offspring that will do the same . but the hound breed have been bred for these traits for hundreds of years . and the plotts are known for their grit and bottom . just my personall thoughts on the matter .
