The only correctly coated dogs bred to work with all the relevant health tests done will not be the"Alsatian"type, most people in Obedience who call their dogs working type breed longcoats & most do the basic hip scoring.
I personally would not want any GSD bred from the so called UK working lines, because the vast majority are longcoated & have known genetic conditions in their pedigrees that are not written about..
The only real bred for work GSDs are those from the continent from VPG/Schutzhund lines. They come from lines with generations of health/temperament/proven working ability dogs & have characters to die for-biddable yet with a very high work drive.
There are several lovely
VPG dogs at stud here in the UK which are also working VPG over here & on the Continent.
Not all
German dogs are of the show type
