Huh. I do know that one day I looked out my front window and saw our neighbor's mule and dog walking down the road. Apparently, the mule had gotten out and gone I don't know how far down the road, but the dog was walking him back to their place. They were just strolling down the road, side by side, like a little old couple. I went out and walked behind them to be sure they got home safely (it was just about time for the school bus to be coming from the other direction and we have a lot of blind hills) and put the Mule back in a pen (figured the dog probably might have to draw the line at opening gates, lol).
