I am looking at the Don Sullivan perfect dog training ads on T.V. I would like to know if anyone has used this system and can offer any advice or knowledge about it or any good solid training program?

Must be something in the air- someone on the Elkhound list I'm on was just asking about this guy, too. Here is my response to her:
I saw nothing special about the stuff he was selling, nor the way the dogs were behaving "after" training (probably because that's the way I expect my dogs to behave and they do/have). You don't need "fancy" stuff from an infomercial to train those
things- a simple collar, leash and piece of clothesline works just as well.
