I have a crazy-mad chewer at home, and an occasional chewer too. Upon arrival, I quickly unwrapped the toy and looked at it. It is covered in little bumps that look very easy to chew off, so I was a little skeptical on how this would hold up, but I like it because it cleans their teeth. I gave it to the occasional chewer, and she sniffed it before slowly grabbing it, chewed a little while, and left it alone. She hasn't chewed on it much since. The crazy-mad chewer likes it, but not as much as the other bone. He was chewing it one night and from the sound I thought it would be gone in the morning, but no, it is still holding up pretty well. A few of the bumps have come off, and some are stretched, but overall it is doing well for my dogs...and protecting things I don't want them to chew on.
