just my opinion reuben but if you take a top litter of pups and spread them around vairous owners of vairing capabilities you will have and i will bet my left one, you will have dogs of vairing skill but the owner my think his dog is ok or a cull then compare these against there litter mates. and you get there are so many culls for the reason of the enviroment they have been brought up in rather than there breeding
Dead on. This is where the rubber meets the road.
