I originally bought an E- collar to train our new golden puppy. We have had dogs for forty years and are getting to old to do things the hard way if we don't have to..... The collar has worked so good that we now put it on other dogs that are visiting for a week-end so we can stop them from jumping against the door, barking at neighbours or chasing our chickens. It would be the first thing I would try on any dog that was a family member.
