well never seen the vid, but he sounds like he trains on over the top (dominance)=fear . When dogs are scared of you, they never really work well for you, they have one eye on you all the while, so they dont get hit .! and dont work proper . And ive had it with dogs, that you have come to heavy on them and they (never) forget, so the dog never works proper. You got to i think be in control of the dog, but be fair with it. The best way to train a dog is with your mouth, not a kick up the arse or wack round the head, when things go wrong, and they do with all dogs as they grow up .Bryn
