Great dog toy
Size: Medium (1 Pack)
Sturdy dog toy that works great for fetch. The ball fits in the medium size chuckit thrower. We have had them for over a year and my dogs love to destroy toys

Pupper’s favorite
Size: Medium (1 Pack)
My dogs love all things Chuck it! And this did not disappoint. I was concerned that since it was made of color scraps it may come apart, like the orange ones do. I have 2 serious chewing Belgian Malinois. But so far this ball is staying the distance and boy does it bounce!

This ball is heavier than the original.
Size: Medium (1 Pack)
The ball is heavier-duty. I love the colors but my dog (border collie mix) and I are not a fan of the extra weight. He didn't like catching it and it was harder to use with Mr. Chuckit. He plays with it in the house. I would highly recommend it for big dogs and big chewers!
