The best advice I can give is find a good trainer now who can explain what aggression/dominance is and show you how to work with a very NORMAL Doberman puppy in appropriate manners. You are setting yourself up for a very hard long road/battle using the methods you are using (and they aren't working).

I would also like to add that I will continue to practice these positive techniques rather than forcing him to submit.
As the day goes by he has already tested me by biting both my thighs from behind while I walked to the kitchen. He just came up to me and bit me on the hands while I am on the computer. I am practicing my patience and I am trying not to take it personal.
BREATHE IN ... BREATHE OUT

Just remember that he's not testing you. He's being a puppy. It's typical normal (although ANNOYING) behavior And change won't happen overnight. I twill with consistency though.
