Nine years ago today, a kind hearted, intelligent, compassionate, clever, and truly good young human entered the world. My son, Ian, who brings to anyone lucky enough to know him, arrived quickly and smoothly that afternoon. Not surprisingly, he is very fond of dogs. When he comes to visit me, playing with puppies and training the adult dogs with me are some of his favorite things to do. For his birthday we gave him a fantastic gift. This very book, or a much older version of it, inspired a great deal of my own love for dogs and academic interest in them at his age. I hope he will enjoy it, too.
