Scout the Ox smells something of interest on the wind.
The deer hide was heavy and we had a long way to go. After several tries Harry the dog allowed me to put it in the sled and Scout the Ox pulled it the rest of the way home.
For the next several days Harry may have been the happiest dog on earth --- carrying this thing around and chewing it to bits!
(No this won't cause a dog to chase deer. It's the excitement of "the chase" that causes that. Our sheep guardian dogs regularly ate dead sheep without it causing them to kill sheep.)
