SHORT-game Ball Launcher … love it!
Yes, this is a smaller ball launcher … It is for her SHORT Game! Love it AND the squeaky baseball that came with it is A-HIT!! Our black golden doodle, Josie, carried that around for hours … batting it around, jumping on it, resting with it right-next-to-her. For your pup’s LONG game, purchase the longer launcher. GAME-on!

Works great with tennis balls
I have a pretty large yard, and this thrower is great for my little Jack Russel puppy. It even picks up ball without having to touch all the spit.

Good toy for dogs
This is a great toy! I do wish the handle was a little longer because I do not have a lot of upper body strength due to health issues. I can still throw with this further than I can without the launcher so my dogs really love it and get excited any time I get this out!
