Dog Health Questions: Becoming a dog trainer?

I'm just wondering if anyone know how someone could get into dog training/rehabilitation? Kind of along the *tv shows* Dogtown or Dog Whisperer line. What if any schooling goes into it and how would someone go about getting a job at a dog rehabilitation center?
