My dog absolutely loves this. He chews on it daily. It really keeps him occupied for for a good while. I highly recommend.

God but..
Size: 4 Inch (Pack of 2)
My small dog loves these. None of the bones are as tough as they say. I have to change out about once a month. It gets a little pricey but they can swallow the pieces once chewed a bit.
