What a beautiful photo of a GSD, the way they are supposed to look - at least until the idiots at the Westminster Kennel Club got involved.
Now most USA GSDs are bred to practically walk on their hocks, and as a result, they can’t work, and need to be imported from abroad.
You can still find "traditional" GSDs at New Skete Monastery, but more and more LE agencies and the military are trending toward Belgian and Dutch Shepherds to get the work done. Schutzhund competitors are keeping some decent GSD lines in tact, but are doing so mostly through importing directly from Europe.
