Total waste of money
Color: Classic, Size: L 3.94 in (10 cm)
I seldom write reviews, but save your money as far as I’m concerned. Maybe mine was faulty. I don’t know. But it’s hard as a rock and too big for to my Australian Shepherd to get her teeth around. It barely made a noise. Maybe I misunderstood the description, but I bought it for her because she’s blind and yet loves to play fetch so I thought it was going to make enough noise for her to find it, but it was a total bust at least for me.

Very Disappointing
Color: Classic, Size: S 3.14 in (8 cm)
The ball is a hard plastic; not flexible at all and uncomfortable for my dog to pick up. It makes NO NOISE while rolling across the floor. I bought it for my newly blind dog because other dog owners said their blind dogs can track the squeaky noise and follow the ball. How... when it doesn't make the noise it's supposed to? It works only if I shake it, totally defeating the purpose. It would be difficult for my dog to chew on the hard plastic, so durability seems pretty good. It's also a nice looking toy, and I think it's safe, as there are no loose parts and the squeaker would be difficult to get to for most dogs. My dog WANTS to enjoy it, but she can't.
