Ok today I got Hannah some beef rib bones and I don't know if they are recreational or RMB's. There was a lot of meat on them but the bones were really hard and she didn't chew the middle part (the hardest part) of the bone she just cleaned the meat off and hid it under our kitchen table . The bone didn't look like something that I would want her chewing up though. Are they considered RMB's or recreational? Is this something I need to watch and take away from her when she gets the meat off?
