Dominance is not a bad thing. It is merely the assignment of pack structure. This is necessary for a happy home that contains canines. There is no requirement for fighting, bloodshed or even arguments.
DOMINANCE CHALLENGES:
This is a normal part of growing up. Most dogs, especially Akitas will test you for dominance much the way children do. Be firm and consistant in your corrections (no hitting!) and be quick to praise lavishly when he submits. It's a good idea to follow up with a 5-10 minute session of obedience (sit, stay, heel, whatever he already knows), also with lots of praise for correct performance.
My method for dominance challenges is to growl back(once) while towering over his head, with my hand resting on the top of the muzzle. Stare directly into his eyes.
