It sounds like fun. We play a version of that game called "Who's faster?" She has to try to pounce on the ball (or ice chunk if we're outside in winter) before it gets by her. She gets ready when I say, "Who's faster--Poca or the ball?" Then I say, "Ready?" to get her excited. If I count she gets more excited waiting. Then I kick the ball, trying to get it past her. She usually wins. She brings the ball back and then waits for me to kick it again. The hard part was teaching her not to crowd me. I had to teach her to back up to give me room to kick. Never thought to teach her a position, which would have been helpful. A better solution than me backing up, which I sometimes do.
