Our dog sometimes lifts his left leg and sometimes it's his right leg to relieve himself. He'll even go back and forth trying to determine which is the better leg. I wanted to know if he had a preference. My initial count was 6 left leg lifts and 2 right. This is incomplete data because we walked down the street where there were more things on the left. I'll have to see if there's a preference when I walk a different way.
