I was just thinking, if you want the bones for teeth cleaning. It's better to stick with brushing daily, greenies, frozen towels, etc. If you want the bones for the nutrition (although you shouldn't need it if your dog already has a balanced diet), you could grind them up into powder. I don't feel too safe using whole bones for kai so the moment I have enough money to buy something decent to grind up the bones, I'll do just that.
