These are great for the dogs to chew on and they are not real expensive.  We have two mini-schnauzers and a goldendoodle who all like them.  They have little bumps on them so they aren't smooth like some Nylabones.  We ordered three of them and because you don't get to choose what style you get, we got two of the same.  It really didn't matter what they looked like because the dogs like them.
