Rascal has his own rules for playing. We have never been able to get him to bring the ball back when we throw it for him. His idea of a game is - we throw the ball and then he keeps it and we have to get it from him. It's been a little exasperating - we've spent his whole life trying to get him to bring it back. However, now that he's teaching us, we're learning how to play!
God bless you, Diane
