Read a great article in The New Yorker about Cesar Milan, aka The Dog Whisperer. I loved reading about what this guy does at his Dog Psychology Center. Here’s more information from the web site:

Cesar Millan teaches that, in order to properly fulfill both our dogs and ourselves, we need to become our canine’s calm, assertive pack leaders. A dog that doesn’t trust its human to be a good pack leader becomes unbalanced and often exhibits unwanted or anti-social behaviors. Cesar does not “train” dogs in the sense of teaching them commands like “sit, stay, come, heel,” – he rehabilitates unbalanced dogs and helps “re-train” their owners to better understand how to see the world through a dog’s eyes. Cesar counsels people to calmly, assertively, and consistently give their dogs rules, boundaries and limitations to establish themselves as solid pack leaders and to help correct and control unwanted behavior. He doesn’t believe in “quick fixes,” even though changing some behaviors can appear to happen in a relatively short period of time. None of those changes will “stick,” however, unless the human acts consistently with his/her dog every day to keep unwanted behaviors from returning. In Cesar’s opinion, no one should ever hit or yell at a dog to correct unwanted behavior.
