When dogs are 'playing' we need to watch their body language in order to truly see how a dog is feeling about that 'play' and to ensure that both dogs are enjoying the interaction. In appropriate dog play, you will see the following signs and signals: Relaxed and loose posture with bouncy movements, Play bows, Turning their bottoms into each other, Role reversal, Fair wrestling, Racing around, Mutual pausing in play, Self-handicapping, Inhibited biting and mouthing, Cocalising. These are called meta-signals and they include play bows, bouncy movements, having relaxed, partly open mouths, curling and turning their bottoms into each other and lying down or stopping to pause play for brief moments. They include play bows, bouncy movements, having relaxed, partly open mouths.
Relaxed and loose posture with bouncy movements, Play bows, Turning their bottoms into each other can be seen in appropriate dog play. Mutual pausing in play, Self-handicapping, Inhibited biting and mouthing are also important signs. Cocalising, which can include barking, growling, yelping and yipping, is also a sign of appropriate play, as long as both dogs are still demonstrating other appropriate play signals.
