Appeasement and displacement. A dog might try to appease another by actively seeking attention via one or more of the following behaviors, muzzle and or ear licking, jumping up, lowering and curving the body, clacking or exposing the teeth, ie smiling, lowering the head and ears or play bowing common body language. Any signal that is demonstrated by a particular part of the dog's body must always be read in the context of whatever other body or vocal language the dog is communicating. Similar signals have different meanings in different situations. So the position of the body and other vocal signals will help you understand a dog's intent and emotional state.
