The white dogs have been around a long time. They are GSDs. Capt. Max said a good dog cannot be a bad color. So Germany chose to dump them, everyone else should follow suit? I don't know. I really don't have a dog in this fight, but I doubt AKC will be willing to register them as a separate variety, because they put a moratorium on adding varieties to breeds. I think it adds up in the end, to more classes, more judging, though that might not be the thought process.
I think it is pretty sad that a new breed had to be created for dogs that exist, and are the same dog, just a different color.
And I think that the breed itself has moved forward in Germany and in America, and most of what I hear about that isn't all that positive. Instead we all go back to the past and say, this is what the dogs used to be like, or this is what schutzhund used to be. But now suddenly we should move forward and get out of the past?
I think it would be a huge mess for the AKC when a breeder has 7 pups and one is white, to either not register it at all, or to register it as a different breed. I just do not see either of those things happening. People used to cull the white ones. Read Winifred Strickland and Jimmy Moses' book, The German Shepherd Today. It tells you it is not so hard if you have off-color pups, but if they are all of equal quality... Do the Germans just cull them so no one knows their dogs threw a white pup? Or have too many generations gone by that the white ones are now extinct over there? It isn't so hard to maintain that they are not registered if they never happen. But people do have white ones here. So what do you do for those breeders, and those dogs?
