My ten month old follows what my other two dogs do....but they are not Dobermans. He greets anyone and everyone that I let in the door with wiggles and kisses, but seems more protective in the backyard when he hears noises (or a bird passing overhead - lol). As he is so young, I am not sure that he knows quite what to do or what he is barking at, but I definately know that instinctually he does watch my every move to make sure that I am ok. The other dogs are barkers and kind of get him worked up - unfortunately - but I am working on that. Mine is a lap climber too - and he is 95lbs....please someone tell me that he will stop growing soon.
