Comes with a fabric covered ball
Style: 14" Length Sport Launcher
Disappointed in this. I have the large size and expected a smaller version of the rubber ball. Instead this came with a ball covered in fabric. The dogs I bought it for won't play with the ball. Maybe it is my fault for not reading more closely but why would Chuck-It even sell something so cheap and poorly made. Dogs can easily rip the fabric off the rubber (which is in two pieces). Very strangely made. Now I have buy a ball to use it.

Launches!!!
Style: 14" Length Sport Launcher
Please note that this launcher is for a smaller sized chuckit - it came as a package deal with an order of small fuzzy chuckits and it works GREAT. Recommend using in dry weather since the water sprays when wet (or just be better at throwing than us!)

waste of money, useless
Style: 14" Length Sport Launcher
Tiny size and matching ball that it slings right in front of you. When it says small dogs it must mean the size of a rat. This is nearly useless. One star for durability since it's plastic.

Great toy
Color: Blue
Great toy, too bad my Shih Tzu is afraid of it. I love the way the movement is subtle and random.
