If anyone is thinking about buying a training DVD by Amy Ammen and/or Amiable Dog Training, I would suggest that you save your money, and not bother. I rented one (Novice Obedience) from bowwowflix.com, watched it once, and mailed it back the next day. Her method of training a sit is to "jerk" up on the collar, while pushing the dog's rear down. Then, to teach the automatic sit, she would heel, stop, and (without telling the dog to sit) "jerk" up on the dog's collar. In the DVD, she had a dog that looked to be about 60-70 pounds, and she actually lifted the dog's front feet off the ground with one of those "jerks". Heeling, recalls, and downs were pretty much the same method. Made my neck hurt just to watch.
