Rachel, if you just ask your butcher for a marrow bone they will know what you mean :wink: Our local butcher used to do them raw but frozen and that was perfect, but now they only do them cooked which as other's have said splinter very easily and personally I would not give them to Piper.
I have just changed Piper's diet to a totally raw meat and bone diet (and cereal for breakfast) and I felt stupid going to buy the meat because I didn't know what I was looking for. I had to wander around the market until I found someone selling breast of lamb with a sign on it - all in an effort not to look daft :roll:
You may find that it makes Molo a bit runny for a day or so afterwards. Also, don't give too many as knawing at the bone itself can, as well as being good for cleaning the teeth, actually wear them down if given too frequently. Mmmmm, might come in handy with the puppy teeth though :wink:
Just my two penneth for what it's worth!
