Don't get me wrong papered dogs are great be cuz you can trace them up and down so you can see what they should be or do. But as we all know that ain't the case in this game allways mixing and match to make them better we cross our line to make a dog. You can have a good standard in a line and stick with it and be ok pure dogs seem to stay consists but some crosses can be good or better. So can straight line but in most cases papers are good for showing or wipe ing lol
If you have the old school line you can do the same with non reg dogs. Butch Arnold's dogs aren't reg and he can trace his dogs all the way back to 1943.
