I think GENERALLY a mature or near mature buck track is wider and the hooves do spread apart when they walk, maybe because of body wieght, So an unusually large doe can have sread hooves also. And they sometimes do it for more support on soft ground or snow. As for dragging hooves I have seen bucks and does do this. The other side of the coin is that my nephew shot a young doe that had comically huge feet!.....
