Bob loves to run around and roll in the snow. We would love to let him just go at it always, but if any of you remember - he is rather an escape artist. My husband has built fences almost all the way around the property and he still escapes (usually plows under the wire fence patches here and there). He even run and takes a running jump and up over the 4 foot wooden fences - when he really wants out. So we have have him on a long lead or be out there with him to supervise and keep him on the up and up.
