I felt it would be worthwhile to respond to a couple of comments. Some reviews refered to Donaldson's methods as fadish or inneffective. However, Donaldson's methods are based on the work of B. F. Skinner, a prestigious behavioral scientist who made major contributions to the field of psychology and behavioral science. Classical and operant conditioning, principals used by Donaldson in her book, have been around for quite some time and have been shown to be highly efective with numerous species. Donaldson's point is that people who train the "standard, leash-jerk" way are ignoring years of tried and true animal behavior science.
Some have said that this is not a good how to book. I don't think that is its primary purpose. I think she is trying to provide a sound foundation on how to think about dogs and training so you the owner are "set up to succeed." The hope is that when you choose a how to book or a training program you will look for one that uses positive reinforcement.
For example, do you see zoo trainers using negative reinforcement with sea mamals or elephants? Of course not, they use treats. Positive reinforcement works when other techniques don't or simply can't be used.
Finally, her point on liking dogs for who and what they are vs. liking them for the human qualities we project onto them is an important distinction for owners to make. I think that this is perhaps the most important point made in the book: what is wrong with a dog being a dog or why do they have to be part human to be good animals/pets?. Changing the way we think about our pets will help us to stay objective and think with our human heads rather than our hearts when we are struggling with training and/or problem behavior in our pets, and in turn to have an experience that is both successful and positive.
