I have a two year old Maremma and he eats mostly raw pork, chicken and rabbit. When I finish butchering an animal, I set aside all of the "extras" for the dog. Basically I give him a hand full of meat, a hand full of organs and a hand full of bone daily. I would say that it's roughly 15% bone on most days. Today he ate a whole pig foot, some pieces of lung and a decent size chunk of skin with fat. He'll eat just about anything as long as it's bloody. Sometimes he'll walk away with it to bury and dig up later. I guess some pieces need to marinate in soil before he's into it.
I have ground it up in the past but as it turns out, the dog is more than capable of doing that work for himself. If you need to use a standard home grinder, I suggest not attempting anything larger than a turkey leg bone. That's just about the limit for most home grinders. Some of the larger "commercial" grinders will certainly do bigger bones than that, though I would probably save those bones for making soup stock. When I make stock, I simmer it for a whole day, leaving the bones in an almost mushy state. They just turn to mush by the time I've gotten all the goodness from them. I mash the bones and then feed that with other food scraps to the poultry. What they won't eat, the dog cleans up... sometimes. I never feed him bones that have been roasted or baked because they can splinter and hurt the dog's digestive system. I almost always end up using those bones to make soup or broth anyway. Then they are all good to go to the birds as I mentioned before.
