Bart Bellon® is the father of modern dog training. His NePoPo® system was inspired by nearly 40 years of experience which encompasses history, education, life experience, politics, and practicality. NePoPo® is a negative-positive-positve system. The NePoPo® system is a system where correction of a
dog does not lead to submission. The negative reinforcer followed by positive reinforcement creates behavior. Due to that, an unpleasant feeling announces a nice event(Pavlov). Later you can use that same negative stimulation in correction mode which will immediately bring the dog from unwanted behavior into wanted behavior.
