i didnt buy the dog for an out cross to my line as i would not put any papered dogs into it, as it does seem that no matter what breed or line weather it be curs, pits or beagles papered dogs seem to be bred papers to papers as was said in a previous post.
Sounds like you answered your own questions right there. It sounds as though your pretty content with what you're already raising. If not for an outcross, may I ask why you bought the dog in the first place then? You spent a bunch of money, so something about the purchase had some potential value to you.
