This is too funny, I also have German Shepherds, 3 to be exact and my one Yorkie Gizmo. Although the shepherds are more out door dogs you should see how they just lay down and get out of the way when they see Gizmo coming when we go for our walk. Gizmo will be just barking and raising all kind of cane at the shepherds, mind you they are secured and can't get to the little one, but still they just bow down to Gizmo as if here comes the boss, it's funny to watch.
