REAL

My definition: is very advanced obedience, tracking with a purpose of finding even tiny articles let alone a body, and protection has to be part of it. 

Schutzhund was designed to prove the breed in Germany and if it is not part of a training program then I feel the German Shepherd dog is not being developed to be a real working dog. 

Herding is real also but not exclusive for the shepherd breed whereas it is difficult to find breeds that truly excel in the three phases of schutzhund like the German Shepherd Dog.
