Why are there adjustable levels of impulse/stimulation?
Different dogs have different temperaments. What works with one, may not work with another. Different impulse/stimulation levels are needed to communicate with them. A level one may work with your dog, but it may take a level three to communicate with your neighbors dog. Additionally, there are times when you may need a boost in the level above the working zone to communicate and control your dog (such as keeping your dog from running into the street or chasing another animal).
