Sleeping arrangements for dog owners?

I let my dogs sleep with me and I have no problems. My female Min Pin sleeps with me every night and has slept with me every night of her life and she is in no way clingy. Some other people say that letting your dogs sleep with you causes the dog to be dominant, this is a load of rubbish. My dogs all sleep in bed with someone and they are allowed on the furniture and I have never had a problem with dominance.
