well, i am nowhere near the expert on rotties as half of the people on here, as I have only gotten my first in the last two weeks. But having raised well-behaved other dogs, my suggestion would be to always remember not to cuddle the dog, etc. when he is exhibiting unacceptable behaviors. To a puppy, it is my understanding that they will associate that negative behavior with the reward of getting that loving attention from you. Instead of holding him, maybe you could just ignore him and leave the room or nicely put him up in his crate until he settles down (as long as you don't do it in a way in which the pup will associate the crate with punishment.) At this age, they really want to be around you, are extremely attached to you and yet at the same time, believe that the world revolves around THEM. Anything you can do consistently to make their world "make less sense" whenever they behave badly should deter future transgressions. You just gotta remember that when you lash out at them, it makes them scared of training, so it is a fine line to walk.
