This dog is performing a play bow, when the bottom goes in the air, the elbows go to the floor and the chest goes low. The tail is held at mid-level, with a big sweeping wag from side to side, often with the hips following. The dog bounces around in front of the human or the dog that it is inviting to play.

The humans are responding in this video and the dog is enjoying himself – asking to be chased. This is a successful game of play until the dog spots another dog in the distance and decides it would rather play with that dog instead of the humans.
