Is my dog showing teeth playfully or aggressively during play?
The behavior by itself is hard to discern out of context. You want to look at body language as a whole. A dog that is playing will have a loose, wiggly body, may hop around or play bow, and may have high pitched growls along with playfully biting or showing teeth. A dog that is not playing will often have a stiff, tense body, be staring down the other dog, low or straight out tail, hackles raised, and with bared teeth may be telling the other dog to go away and leave them alone.
