To my amazement, after a few minutes my pup began to heel alongside me, having gotten the idea that I might just be worth paying attention to. I hadn't said a single word—actions were speaking far more loudly. Over time, I modified the exercise to go in a zigzag path, which kept it interesting for us both. When it came to writing Edgar's story, I made this kind of random, unpredictable walking one of the cornerstone exercises for the Sawtelle dogs. Because it was so simple, it was naturally something Edgar might do to help out, even as a child. One day the word "crazywalking" showed up on the page, from who knows where. I liked that it was an invented word, and I kept it. In my imagination (this is not specified in the book), Edgar was the person to coin the term.
By the way, I do still do some version of that simple exercise with my dog, Lola, though she is 7 years old. It's a great warm-up before we go for long walks.
