Lazy gardner, you can test the collar on yourself as I have, but I think you will find that dogs seem to have a higher tolerance for discomfort than your hand has. I tested up to highest level on my collar and it was not pleasent, though it barely fazed my pup when she went after chickens. Again I may be completely off standard training protocol, but I have found that a stern command followed by a beep (once command was obeyed) and a treat works better. I've been working with her heavily, and have honestly had to administer only a few warning shocks. Every day we start out with chickens in coop and do "drills" with sit, stay, come, and lay down. Then I bring her inside and let chickens free roam for a bit then I bring her outside with chickens and repeat all of the drills. Each time she does as I command I beep the collar and she gets a good girl treat. After that I bring my daughter into the mix to carry a chicken around while I continue the drills. At that point, not only does pup have to deal with possible shock, but my daughters wraith (she loves her chicken nuggets). I've seen marked improvement, given the fact that this dog has killed 3 hens in 6 weeks and 2 back to back. I actually left dog door open today with chickens outside, she had collar on just in case. She went outside, ran around a while, and did start to chase a chicken then changed her mind. I think it is going well so far, though still won't leave her unattended with flock.
