Years ago, a new acquaintance asked me about the bag I wore on a belt around my waist. She saw me taking dog treats out of the bag and feeding them, one after another after another, to my then-young dog, Otto. I was in the process of teaching Otto to ignore squirrels in trees, pigeons in the street, and cats on the edge of the riverside trail we walked each day, and the tactic required a lot of treats. My new friend wanted to know if I always wore the bag; surely, since Otto seemed so well-behaved to her, I didn't need to have it with me all the time? Ah, yes, but would Otto be so well behaved if I had no treats? At that point in time, so early in our relationship no!
