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.

Thing is absolutely garbage. Ball didn’t make it back once! Broke in half
