The German Shepherd in the Us does have a longer back and more angulation. Also in most breeds in the US, a female is permitted to be longer in the back. Its funny you mentioned infertility in Germany, as the US breeders believe the shorter backed German dogs- this is the source of the problem- longer back, more room for puppies.. Wives tail or not- I am not sure, but its long been the accepted standard in the breed here, and accepted more among the females especially.
By US standards, Nicole has a beautiful example of the breed, even if it is not a recognized color yet. When the German Shepherd was admitted into the AKC, varieties of a breed were not as widly accepted, and seldom named seperate breeds. Now that practice is pretty widly done- with varieties based on colors seperated as such into seperate breeds. The most obvious example of this is the Cocker Spaniel. ( Black, particolor, ASCOB - any solid color other than black..) or even the White Bull Terrier, and the Colored Bull terrier. Other than color- the standard reads the same.
With the white shepherd- there is just as much a loyal following, although not accepted yet, its coming into reality of being accepted at some point. The actual debate is not whether to accept, but whether it will be a variety- alias seperate breed, or just accepted in as a recognized color. When the politicians in the dog world make up their minds, I sure their acceptance will be coming.
I do however, find it funny the AKC changed the Russian Wolfhound to a Borzoi, because of relationships with Russia at the time and since then. However- we now accept the Black Russian Terrier. There has been a fight since day one in this to restore the name of the Borzoi back to the Russian Wolfhound.
