Helps me throw much farther and Teddy loves racing after the ball. He gets excited when he sees me pick this up because he loves chasing balls and I love that it's interactive play. I would also recommend getting the whistle ball in addition to the regular balls (I think Chuckit makes one, but I got the Planet Dog one, which does fit in the Chuckit); I don't know if it makes a difference to Teddy, but it amuses me. I would definitely recommend this item and would buy again if needed.
