Ritual greetings are used in coyote packs to confirm the social order. Here a young coyote approaches the Alpha, who is his mother, to greet her with kisses and muzzle rubs. Note that his ears are always back. She seems to only accept it and to put up with it — she does not return the behavior in any way. In fact, the young one did not approach with his usual wiggly joyfulness — maybe because that had already happened an hour earlier?
