Oh Misslala you are just showing your ignorance. Read Culture Clash by Jean Donaldson, Don't shoot the dog Karen Pryor, In defence of the Dog John Bradshaw to name but a few
Dogs do not learn from fear.
Dogs learn from two main principles. Give something to get more of a behavior you want. Take something away to stop a behavior you don't like.
Positive Reinforcement (+R): If you want your dog to repeat a behavior more frequently, reward that behavior in some way.
Negative Punishment (-P): If you want your dog to repeat a behavior less frequently, remove any reward or perceived award for the behavior.
Think of positive and negative in the addition/subtraction sense. The counterparts to +R and -P are negative reinforcement (take away an aversive - something painful or unpleasant to the dog - as a reward) and positive punishment (present the dog with something painful or unpleasant for doing something you do not like).
"Positive training" uses positive reinforcement and negative punishment exclusively. Aversive corrections and positive reinforcements has been proven to be the least effective way to teach
Positive trainers have successfully trained all sorts of competition dogs, from obedience to agility to tracking. In fact, clicker trained dogs are usually ready for the obedience ring and agility competitions much faster than dogs trained with aversives corrections.
There is no debate about Cesar Milan it has been proven his training methods are cruel. He has been banned in many European countries and his tour of this country was cut short. All reputable agencies have dismissed his methods. RSPCA, Dogs Trust, APDT, ADPC etc. There is no argument to be had that the old dominant method of training works. It has been dismissed by hundreds of scientific studies. The case is closed.
With regard to your comment on treats, I do not treat my dog all the time although no problem to me, I would rather do that than kick dogs, like Cesar or strangle them or hit them etc.
I teach the a new behaviour and mark it with a click and treat - the dog learns the new behaviour - job done easy peasy!
