I had the same question. Came here, everybody said good things. I figured i'd get one eventually. Then I actually found one and it's probably my favorite thing ive ever bought for buster. I love it and from the looks of it, so does he. He'll chew on it for hours. Petco is no help, they looked at me like i was a weirdo. I went to a random almost pet store outlet type place and they had them in all shapes and sizes. I got a buster a great one for like 8 bucks.
