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.
