I don't want to start an argument, but just for the purposes of information, the lowest levels of stimulation on this collar are less than what you would feel if you touched a metal doorknob after walking across a carpet in your socks. It is not intended to hurt or harm the dog, but merely to distract, to get his attention. The collar also has a vibrate and beep option, so you can beep him first to get his attention as a warning. After one or two experiences where he first hears the beep then feels the vibration, then the mild shock, there is a very good chance that he will turn away from the chickens when he hears the beep, in order to avoid the other stimulants. After a few more experiences he can learn to ignore the chickens entirely without ever experiencing the shock again. This is how my dog learned to stop chasing cars which was a very big deal for him. I was amazed at how quickly he learned. This process should take place on a long line, of course. The dog learns that HE controls what happens to him, and that if he makes the correct choices nothing unpleasant happens to him at all. It is no more abusive, IMO, than walking your dog on a collar and leash and expecting him to walk in Heel position. But it must be used with intelligence and discretion. It is not a cattle prod.
