Some of you may remember I have a rescued greyhound who used to race. He loves to run so when I had him out this evening we were running. Well, he pulled me right off my feet. Fortunately, I have a lot of experience with falls having raced bicycles in my younger days. Without letting go of the leash I did a perfect shoulder roll. The thought that flashed through my mind as I went down was, "Oh, no, I'm going to tear a hole in the knee of my new jeans." Luckily, I didn't.
