(1) The Other End of the Leash, Patricia McConnell -- as good as you'll get by way of "canine psychology" introductions.
(2) Bones Would Rain From the Sky, Suzanne Clothier -- not really a training book or about dog psychology; more a philosophical meditation on our relationships with dogs, how we choose to interact with them, and what the rewards are of doing so carefully, conscientiously, and with awareness of the quality of our relationships. I reread this book often.
(3) The Power of Positive Dog Training, Pat Miller (if you want a more thorough version) OR Family-Friendly Dog Training, Patricia McConnell (if you want the quicker version and want to involve the whole family) OR The Puppy Primer, Patricia McConnell (if you want the quicker version and have a puppy). Basic training primers, good place to get started with just about any dog.
(4) The Adopted Dog Bible, Kim Saunders/Petfinder.com. It doesn't actually matter if your dog was purchased or adopted, this is a good broad overview of basic health issues, caretaking practices, training tips, etc. Good introductory book that covers all the beginner bases.
(5) Control Unleashed, Leslie McDevitt -- I add this one with some hesitation, because it is really not geared for the novice owner. But the information in it is SO good and SO thorough that if you are thinking of doing any sports or work with your dog, it has to be on your list at some point.
If you want more on "dog psychology," some good pop treatments include John Bradshaw's Dog Sense, Stanley Coren's The Intelligence of Dogs (although his actual intelligence metrics are somewhat controversial as they tend to emphasize trainability over independent problem-solving skills), and maaaaybe Alexandra Horowitz's Inside of a Dog, although IMO it is decidedly second-tier next to the others.
I would not recommend the Monks of New Skete for dog psychology. Not by a long shot.
As far as pointer training goes, that's something you can't really get out of a book, and probably can't get out of a dog that hasn't been specifically bred for it. Instinct is crucial for a good working bird dog.
