Taking the dog to bed with you because it cries doesn't make it the boss. It makes it happy because it is with you, where it wants to be. It has nothing to do with dominance. Dog cries, dog gets what dog wants. Dog cries again. Behavior has been rewarded. It will be repeated.

It's not a battle of wills. It's simple behavior modification. I sprayed Bitter Apple in my Shepherd's face when he barked in the crate. After four reptitions, he stopped and tried something else (lying down with a sigh) and I let him out and gave him a treat. Rinse and repeat- the dog hasn't cried in his crate since his first day here. Some take more repititions than others, and some dogs have genuine psychological separation anxiety problems, and a different tactic is needed.
