It launches balls impressively far, which keeps my pup happily running and burning off energy. No longer having to bend down to pick up slobbery tennis balls! is a huge win! It’s lightweight, easy to use, and surprisingly durable. Highly recommend for anyone with an energetic pup and a desire to keep fetch going without the strain! Just note that it is for smaller sized tennis balls.

Excellent product, but keep it away from chewers.

Style: 2.5" Ball

This is a very strong and effective launcher and could have lasted a very long time had my 9 month old not chewed the ball claw end off. I will buy again.

Our Dog Loves This Ball Thrower So Much

Style: 2.5" Ball

Works excellent for dogs that like to fetch! Our family dog loves this toy. He will bark and jump as soon as he sees us pick it up. The dog next door to us gets excited when he sees us play with our dog with this dog ball thrower. Its that good for dogs who love to fetch and run. Perfect for the young and elderly to play fetch with a pet dog. If you have back or shoulder problems works very well. You don't have to bend down and pick up a slobbery ball. Nope you use this to pick up, grip up and grab the ball. Wish every dog could have this ball thrower in their lives. It has changed the way we play fetch with our dog.
