Nope. Dogs digestive systems kill bacteria. Prey model raw is actually the best, most biologically appropriate diet for dogs. As long as they don't have immune system problems, a raw diet, or a raw meaty bone now and then, is great.
I thought the same thing about the mess, but it's really not a big deal. I put a kitchen towel down on our laminate flooring and put little gates around it and Odie stays in there while she eats. It gives her some peace and quiet from the cats who are always interested in what she has. Now when she sees me get a towel, she goes running to her spot!
