Im a little confused about using some RMB's like the larger ones that are weight bearing. I assume you just take the bone away after the meat is gone but how long do you allow them to work the bone. Prior to coming here i didn't know this was a real problem and have always let my adult shepherd (female) and mixed breed(male) chew on venison legs bones. Prior to his passing at age 11 his teeth never looked to be wearing but at 7 hers do. And he seemed to be a much more powerful chewer and would crush them to access the marrow. She could to some extent but not as well.Should i just not use these at all. That would be a shame as i basically have an endless supply. How I do use marrow bones without damaging teeth. What about antlers? Are bully sticks appropriate for raw feeding puppies? What can i use to keep the new guy busy while im doing my morning routine. Im really worried about messing up the calcium phosphorus levels. Also are chicken backs and thighs appropriate for a puppy? Sorry, lots of questions in there. My puppy coming next month and want to do raw feeding but dont want to mess him up.
