Cesar goes by the "positive enforcement when needed and negative enforcement when needed" principal. Basic psychology and its amazing how it turns killers into teddy bears.
Have you read any of his books? I definitely recommend "Be The Pack Leader". It is a very interesting book that goes deeper into his methods and how he uses psychology as a training technique. It is designed to give you everything you need to know to turn a dog like Khloie into a dog like... uhh... your other one.
i've not read his books - i'd like to, though. his story is pretty amazing... he was a fence jumper and didn't speak any english, and didn't know anyone. he got a job as a pet groomer, taking all the aggressive dogs no one else could handle. and - what's most amazing - he's completely self taught.
thanks for the recommend...i'll check that one out.
