NectarMom,
Sorry to hear about the situation. I didn’t think that “fat” had proteins in it. So I’m not sure about an intolerance other than from the amount of fat itself. Maybe a limited amount of time with the marrow bones at first and then slowly let them have it for longer periods of time. If you think your dogs can’t have the marrow bones, you can get the marrow out by boiling and stuff the empty bones with something else so they can still gnaw on them – like yogurt or even stuff some of the Darwin’s turkey in there and refreeze so they have to work to get it out.
