There is a lot of great information out there about dog behavior and training. Here are a few resources that I recommend.
"The Other End of the Leash" by Patricia McConnell (All of McConnell's books on dogs are wonderful and highly recommended, but this is her most well-known.)
"The Culture Clash" by Jean Donaldson
"Don't Shoot the Dog" (and "Reaching the Animal Mind") by Karen Pryor
"The Power of Positive Dog Training" by Pat Miller
"How To Behave So Your Dog Behaves" by Dr. Sophia Yin
