This book was recommended to me many years ago when I asked for advice on a dog forum for training my corgi mix myself (without a dog trainer). I was told that Pat Miller really is one of the best in the field, and when I purchased the book I was not disappointed. I found it at a used bookstore for a dollar or so, and was told I was really lucky to find it there and so cheaply, too. Upon reading it, I understood why. This book guided me through my early years with my corgi mix, and because of it I was able to train her entirely at home with very little outside help other than the book. It is very easy to read, and easy enough for even a novice dog owner to understand. It covers all the basics - from sit, stay, to even jealousy in multiple dog homes - and six years later (give or take), Sandy is still a very well trained, mostly well behaved (except for some barking that we have made progress with over the years) dog. I keep this book on my shelf, and even now will refer to it sometimes if she presents any problem behaviors. It speaks a lot about the clicker, but you could do most of the methods even without the use of the clicker and still be as effective. The book was really wonderful. I bought many dog training books when I first got Sandy, but this was the only one that I read all the way through. Most others left me dissatisfied, and wanting more (wondering "So, now what?"), but this one spoke to me not as though I was an expert in dog training, nor as though I was completely stupid to dog ownership (I find both of these are common ways of addressing the reader in dog training books - I am not a professional dog trainer, but I am no novice in owning dogs, either), but rather as an equal. I really enjoyed that aspect. Pat Miller knows what she's talking about, and she expresses and "trains" it well. I recommend this one to new dog owners quite often, and most of them have been thankful for the suggestion finding that it helped them, too.
A few more things that I would like to add is that it, also, has resources listed in the back (links to more information on clicker training, video links, etc) which were very, very helpful. It, also, has a chart in the back for tracking training. I loved this aspect of the book, and Sandy's tricks are charted in the back. Even today I can look at it and see how fast she learned.
