My dear friend Jackie bought Katie an iFetch ball launcher. You can set it to go ten, twenty, or thirty feet. Katie needs to get used to the ball, since she usually uses tiny bouncy balls, but I am trying to spike her interest in them. Jackie's Yorkies ran like crazy chasing the balls. The tiny Kong squeaky tennis balls also fit in this. It's really great.
