Sawyer's obedience trainer suggested the Easy Walk harness as an alternative to the prong collar. Sawyer was walking well on the prong collar, but when he became overly excited by another dog or a squirel or a child or whatever, he would strain at the collar and sometimes yelp. I was somewhat skeptical about a harness because I have seen dogs that where them tugging their owner's along, but this harness, which clips in the front, works on their oppositional reflex. With minimal correction, Sawyer was heeling and it easier for me to control him when he wears the harness. Just wanted to share...
