Terrific toy for heavy chewers
Size: 6 in, Color: Blue
My dog loves this! Chews and plays with it constantly. These will last a long time, however, eventually they begin to break down. THEN GET ANOTHER, lasted a couple months with constant chewing.

My dog doesn't like it
Size: 5 in, Color: Orange
My dog wasn't a fan of this at all. He was curious about it, probably because he could smell it, but he wasn't sure about chewing it. It could be because his teeth squeak against it? Or maybe it has an odd texture? I don't know But this has sat in the toy bin untouched since the day we got it
