I have to agree with what everyone else has said. We have been using a behaviorist for Tucker for several months now and we were concerned at first because some of her beliefs are rooted in the dominance theory. However, her methods are kind and very effective, rooted in logic and what works. She has an honest affection for animals, ours included, and she alters her methods for each animal. Tucker is very submissive and his agression and guarding behaviours resulted from fear and not "dominance". By approaching Tucker calmly and gently, only after he has calmed down, it has resulted in him calming down considerably. He now knows that the calmer he is, the more attention he gets and faster. As for furniture, dogs are pretty clever. Tucker is allowed on the upstairs recliner, only after he asks for permission and it's granted (he places his head on the edge of the chair and begs with big sad eyes!). He is never allowed on the other furniture and would never jump on the furniture at someone else's home unless invited. As for our bed, Tucker will snuggle up with me when I read but he knows that when the lights go out it's time for him to head to his own bed in our sons' room (not on our son's bed!). It's amazing what they'll adapt to if it's made routine. Our trainer has also shown us that, with submissive or high-stress dogs, routine is incredibly important. Tucker seems to be much calmer now that he knows what's expected of him and that we are firm with the rules that we've set.
