I found this ball 6 years back in a pet store while looking for a high energy toy for my Aussie. He was a puppy at the time and absolutely loved this ball! There is no other ball he'll play with! So, I stock up 10 at a time! I only wish the slingshot was stronger. A good tug of war with another dog, and it's broken. Benny loves this toy so much that, if someone throws it up high and it gets stuck in a tree, he will sit near the tree and just stare up at the ball with a sad look on his face. As soon as I give him another one, his whole world is better!
At first I thought it came with the launcher! But I was very surprised when it was opened!
Besides that mishap, my dog and I love this toy! At first it is a little hard on your thumb but gets easier! My dogs love it a lot more than tennis balls!
