The other day I was taking my puppy for a quick lunchtime stroll around the neighborhood when I noticed a loose dog. Fortunately, I saw him before they saw each other. I turned around and darted into a cul de sac where we would be out of sight. But then I was stuck. I kept peeking and the dog was just meandering from bush to pole to garbage can. We were in the back of the subdivision and the only way home was to walk past him.
