Keeps her busy!
Color: Medium size (5.9")
Our Molly loves this. Only thing is that it is a little too big for our Maltipoo, but she still tries to keep up with it.

Tough
Color: Medium size (5.9")
So far my dog hasn’t destroyed it! And it’s been a month. So I call that a win. Plus he loves it.

Perfect for active dogs
This is a must-have if your dog loves to fetch. It throws the ball far with very little effort and keeps your hands clean—no more slobbery chuckit balls.
Lightweight, durable, and makes playtime much more fun (and less tiring for me!).
