As I write this, I have just come back from a day at the 2011 World Herding Dog Trials in northern England. I was in the UK once many years ago, watching the International Sheepdog Trials. I was just getting started with sheepdogs and had not yet begun to work as a behaviorist. Over the years, I’ve learned a lot, and I hope to learn a lot more in the future. But the lessons I’ve been taught by herding dogs are as timeless as they are valuable, and are a fitting subject for my last regular column for The Bark.
