Yes! But it depends on how you use them. An intense static shock is obviously an unpleasant experience for any dog. However, our positive ecollar training method relies on a very low level stimulus. Because the level is just enough for the dog to notice the new stimulus, the dog feels no pain. Our dog obedience training teaches the dog that the stimulus means good things – not bad. Like Pavlov’s bell, an ecollar paired with a treat can have pup’s mouth watering in a few days.
