Great for small dog fetch
Style: 14" Length Sport Launcher
We love this for keeping our hands clean and saving our shoulders while playing fetch. Not sure why this size is so incredibly difficult to find (not in any stores in our area). It fits both the small rubber and tennis ball types. We have a 15lb rat terrier, and he loves it.

Ball is very small
Style: 14" Length Sport Launcher
It says it’s for small dogs up to 15LB. My doggie is 15 LB and this is way small. It’s a tiny ball. If your dog is 12LB to 20LB I would get the next size up to small.

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!)
