Good or Not good, depends on what your values are as much as anything. To me positive training werethe dog wants to work for you is good. I don't think a dog should work due to fear of correction. That is not to say correction is wrong. I'm talking about how it's used. Too often a great dog will be ruined because of unfair & over the top correction. You really need to go see with yout own eyes and learm what these people think about how to train a dog. I do think to training as a helper usinf thier dogs that are already trained is the correct way to teach you. They understand thier dogs and know howthierdogs will recat. This way they can give you as much dog as you are ready to handle at that point in your career. I would only allow a very seasoned helper work a young dog for me as too much pressure on a young dog can create problems that take years to correct. There isn't anything in the videos that would inluence me drasticaly good or bad. Remember that everyone puts thier best out in advertising and all video can be edited.. The true test is how theyt handle the problems. Go meet these peopke and seewhat they are all about. Let us know what you found. If ytou have specific question after that maybe we can help.
