My little one goes to town on these.. I have bought several.. I get scare when he chews all of the end down and then looks like little pieces of the fiber are coming off. so I throw away and buy a new one.. at least they are cheap enough to do that for cost. He loves them and nothing else gets chewed.

My dog loves it, he’s a Boston Terrier. Perfect size for a Boston. It is well made, doesn’t fall apart and there is no stink! Safe to let dog use by himself and good value for the money.
