@Breffni-Potter I never really liked ceaser's methods as he use physical methods to keep dogs in control. I like Zak george which really helped me to train lexi few tricks real quick but without being aggressive or through punishments.

Another thing my trainer today suggested is to read http://www.amazon.com/The-Dog-Vinci-Code-Training/dp/1843583070 which basically not only help to to train dogs, but to know more about their behaviour. I am going to check if this is available at any local stores, if not order from Amazon
