I don't do raw, but we do feed marrow bones (I have my butcher cut shank's in 3/4" thick pieces) - make stew for for dinner and give the kids the cleaned bones. I also give them ribs from a standing rib roast. These two bones are both cooked, but they are heavy, thick bones and they don't splinter. I have had some of them gnawed on for a couple of years now. When they start smelling nasty, I just put them in the sink wash them with hot soapy water and rinse well.
For an added treat, I rub peanut butter inside the hollow marrow bone. |
