Neat recent theory about dogs: A year or two ago it was theorised that the reason dogs tilt their head when they are being spoken to is because they are trying to see more of your face, or more specifically the lower half of your face, in order to better read your mood. A dog has a muzzle/snout and this means it's eyes only pick up 50% of what is in front of it, the lower half of it's vision being just it's muzzle, when a dog tilts it's head it can then see both your eyes and your mouth at the same time and better understand your mood/commands. The dog is basically working it's way around a built-in handicap, that of having a long nose.
