Well, are you talking about 'dogs' or 'shepherds'? There are some things that seem to be unique to shepherds. One is the sometimes often vocalizations over EVERYTHING. Two (which is good to find out now) is that they can be drama queens... males more than females in my experience. Grim has carried on like he was dying because my Pug pushed him into a piece of furniture when they were rough housing.
He shakes it off and goes on running around like a maniac, but I can see a non-GSD person rushing him to the vet right off. They just have some little things that are all their own.
