I have only heard that they are super stinky...I wouldn't use them just knowing what horses step in for most of their days LOL
If you want a good chew for your dog, get raw beef ribs. They don't have a whole lot of meat on them, what there is is good for your dog, and the bone part is substantial enough that they last and provide quite a good bit of marrow. They are not weight bearing bones, like most of the marrow bones on the market, so a cracked tooth is not something to worry about with rib bones. That is what we give our girls when we want them to chill out and chew something :biggrin:
