Made of keratin, Empty Hooves are far less likely to splinter than processed bones as chewing on the hoof will grind it down slowly. What makes them even better is due to them being empty, they can be stuffed with things such as - Anco Pate/ Peanut Butter/ their dinner - to make them that little bit more enticing. Or you can just simply let them enjoy the hoof on its own, they are bound to love it either way.
