They should be spoiled! You need to be the leader of his pack, then if you accept new people, he will to. He has to decide you are, and with him sleeping with you or under the bed, he has. Every dog has to have 'his' job in the pack, mine guards me...day and night! Sounds like this one is doing the same job by sleeping under your bed. With that 'job' comes security, because he Knows what he is supposed to do! Encourage it, and praise him when he gets it right; and he will be one happy mutt.
