German shepherds, rottis, and dobermans main purpose was to serve and be guard dogs- this is not the same thing.. not at all.. I had all but the rottie in earlier years but they are guard dogs and socialization and training does it. This is not the same- not at all.. Just like the bull dog was once considered aggressive until the club took hold to change the breed, this wont happen until the clubs do the same thing here... You take care.. moving on now..
