Thanks for the links! I didn't check them out yet because they're in another window right now (eh, I'll do it later). I just need a super quick answer, what about the size of the ball? In order to catch the ball and NOT dislocate his jaw, Lucky needs a smaller than average tennis ball LOL!!! It sounds like he'll be pretty good at it. We just need to pick up some speed ! I bet the Papillons'd be whizzing by while Lucky takes his grand ol' time. I'll definitely look into this.
