K3587 answered Monday July 13 2009, 9:07 pm: One thing it seems some of the former answers have missed...the reason it is a sign of affection is because the dog thinks they are grooming you. When my border collie starts licking my hand, she'll systematically cover every inch of my arm until I stop her. It's her way of cleaning me and straightening my hair out...not that I'm especially hairy, but whatever.
