We have a 8 month old male Doberman that needs lots of exercise and likes to chase a ball unless he gets distracted by a pretty little Boxer, Dalmatian or whatever other female is within 500 feet of him. We have a huge dog park that opened recently near our home and this has been a activity for us to enjoy there. This size might be overkill because you can really send the ball flying but with a little practice it works great and gives you plenty of options. My wife sends the ball about 50 yards and she is petite. I like the fact that I don't have to pick up a ball with slobber all over it anymore.
