Appeasement, submissiveness, etc. There's a great DVD out there called "The Language of Dogs; Understanding Canine Body Language and Other Communication Signals" by Sarah Kalnajs. Two-disk DVD with lots of footage showing all sorts of body language under different circumstances and degrees of stress and among various breeds.
