I think this is a great product. The bones have a very pleasant smokey aroma and I didn't think they were messy or sticky. My dogs loved them, however once the marrow was eaten, they had no interest in the bones. I am still giving a high rating because they are well made and come losely wrapped in brown paper.
My dogs only chew on bones that they can get some morsels off of, and these are just to solid for there liking. I am hanging on to them for my daughters dog who I am thinking ...
