Awesome dog toy
Color: 3 Colors
Theses are great tough squeaky dog balls. Last a long time unless the dogs lose them outside,. Just the correct size for a german shepherd.

A little too hard for our dog.
Color: 4 Colors
These are definitely durable balls. They are a harder than our dog prefers. He does play with them a little and enjoys squeaking them, but he doesn't like to play fetch with them and that is primarily the only thing he really enjoys doing with balls.

Dogs love them!
Color: 3 Colors
Dogs love them! Larger than your average tennis balls, satisfying for my dogs to chew on, the squeak isn't too annoying, colorful enough I can find them in the bushes.

Great product at a great price
Color: 3 Colors
I bought these for my heeler/border collie mix. She destroys every toy almost immediately. They are her favorite toys and plays with them daily. They are still in great shape after 4 months. They have a squeaker, but it is not one of the obnoxious loud ones.
