I'm curious about chews for my dogs. There are quite a few things that say chews and a lot that say treats. I want something that they can chew on any time they want, but is not something they are going to totally eat while chewing. I don't know whether to use those white rawhide chews, or the nylabones. Neither seem like good options. I just don't see any reason to give my dogs plastic. My 3 small ones are raw fed and can eat some bones, but I want something that is just for chewing and not for a meal or treat. Any suggestions? Thanks a lot in advance!!
