Ok
Size: 5.25 inch (Pack of 1)
My pups not overly interested in it. If it had some texture it would be better. The price was right though, and it gives him some variety in his toys.

durable. interesting shape
Size: 9.5 inch
I like that chew bones come in a variety of shapes. This shape is currently not my dog's favorite but that is ok. She plays with it a bit. It is durable and she will get around to it sometimes.
