Yes, now the protective instinct has been added to the long list of health problems . lol. It's so sad it is amusing.

Here is a nice video of some modern show line dogs. I will be happy to embed it if someone would tell me how. These are all progeny of the 2007 German Sieger.
Big or small, "old fashioned" looks better with each passing year. The title of the song playing is QUITE appropriate. "Fix You"....
BTW, for those in this thread confused about sloped backs etc. This video is an EXCELLENT example of what is causing it. Look at the rear leg on just about every dog in this video. The rear leg is much longer than most normal looking GSDs. The bottom of the stifle, ( curve in the rear leg), runs parallel to the ground for about 2 to 3 inches. It is not supposed to do that. That is a big contributor to the "slope" you are talking about but since that didn't seem to do enough for these breeders, we now have the rather significant drop off right in the middle of the back.
This video I find to be exceptionally sad.
