Your dog will think you've been working out the first time you use the Chuckit!.  You can really hurl a tennis ball with one of these!

Now you can get your dog the exercise he needs without throwing your shoulder out in the process.  Even better, you can avoid the whole slobber issue.  You never have to touch the ball, 'cause Chuckit! can pick it up also. 

Chuckit! works with a standard tennis ball, or the colorful Chuckit! Fetch Balls.  (One ball is included.)
