IMHO, if you get certain color of dogs most of the time. Then up pops a puppy or two that is totally different in color from the rest. Is usually wise to hang onto them and see how they turn out. They make very good dogs, these throw backs sometimes can be bred back into it's same bloodline. Giving the bloodline for a lack of the proper word, hybrid vigor. Without going outside your bloodline and introducing another entirely new set of genes. Cheers[/QUOTE]

Very interesting.
