Borzoid, I really don't know much about the american show lines, we were dealing mostly with the german lines. But I did notice the difference in the pictures. The shepherds don't have to be stretched out as much as the white dogs to be stacked, it just looks more natural. I would be more concerned about the fertility issues since all our german friends do not favour the whites because of health issues. I'm still into some different sites studying genetics, most of the sites so far say white in shepherds is a recessive colour??? I haven't met any white shepherd breeders since whites are generally frowned upon . Why would you want to own a dog that was not accepted by the AKC in the first place?
