Tommee: I'll take it from your terminology that you don't show, yourself? Correct me if I am wrong?

In reply to your first comment: Yes he does advocate the use of a slip chain, but its like anything - there are good and bad ways of using any equipment, and the methods he uses do not include rough handling. I have seen far worse at pet dog training clubs, with people hauling on dogs whilst trying to train them. I personally use a half check on mine in the show ring and a plain flat leather collar for walking etc.
As to training dogs from puppies, I do train mine as puppies - from 6 weeks onward training begins - firstly just getting used to being handled all over and moving on from there to socialisation and lead training. My dogs are always well schooled when going into the ring - something often commented upon in write ups, following wins. I also compete in obedience and rally so I do know how to train a dog! However some breeds can be very difficult and so a bit of help is always useful. If you actually saw the people who go to Eric for help, they are experienced show people, who often have a specific issue with a specific dog, or with their own confidence.
Do I put down my dog winning to a single lesson? Obviously I do not put that session down as the sole reason for the success - however what it did do, was give me another perspective on the attention span issue and thus some more tactics to add to my repertoire for dealing with it. After all we can always learn something new can't we?
