Great for a small dog.  I wish it collapsed, though, like competing brands do.  My 7.2 lb toy poodle is too small for the small chuckit balls.  She is very hardy and tenacious but we use smaller squeak balls that are kind of squishy, and fit into the Chuckit launcher.  I'm disappointed that they don't make squishy/smaller Chuckit balls.  Tiny dogs like chasing balls far, too!
