She does love a bone. This one brought back from the supermarket, one of two in a pack, a couple of weeks ago at least. The meat attaching and the marrow within were made to disappear within an hour at most, but the bone really has gone on and on, we still often hear gnawing sounds coming from her corner, though there's nothing left on it at all. The other one is in the freezer still, for a rainy day.
You can take it off her though, no argument. Such a good dog.
