I have an 8-pound toy poodle whose passion is fetching balls.  Her mouth is so small she could not get the regular chuckit ball in her mouth and carry it very far.  I ordered this mini-chuckit and though the ball is a little bigger than her very small balls, it works fine and she catches it in her mouth as it's heading toward earth. I have noticed that this mini-chuckit hurles the ball much farther than the regular, which is great because she loves to go far to fetch it.  We use this launcher several times a day and we never get tired of it.  The ball it came with got trashed within a month so I bought Tuff Balls to replace it.  We absolutely love this launcher.  It's fabulous for the beach.  You can't go wrong with this if your little toy dog loves fetching.
