Query: Ok, but a little too soft for our dogs

I don't know what it is about the white colored nylabone material; it is just so much softer than the yellowish material. Even though both are labeled "Dura Chew" The dogs have not yet taken off sizeable pieces of this bone, but they can leave pretty clear tooth markings. This chew needs closer monitoring than the other nylabones we have bought.*************UPDATE: It is a little more than a year since I first put up this review and I just bought a liver flavored Nylabone that is also made from this white colored material. I'm uploading a customer photo to show the difference. If you have a dog that is an agressive chewer, you may want to stay away from the white nylabone material.
