Ok sorry i have a bit of a silly question here basically i just want to know if anyone here gives there dogs or puppys raw marrow bones

Reason i am asking is i can remember clearlly my older collie many years ago chewing a raw bone happily for hours on end with no problems yet just googled to make sure my pup aint to young to have one it said never give marrow bones to dogs uncooked yet next says never cook as if cooked can splinter and harm the dog

Anyone please help me on this one
thanks
