Seems the only thing the two share is the distraction part. Like I've said before, you would have better luck making a wall sit and be soft than getting anything from Kona when she throws a switch. And she wont have a clue one what she done wrong either.
As for the trainer, well I figure he can be anything he likes to be. A member, a punching bag, what ever suits him best. I have no issue with others opinion long as they dont have issue with others opinions. Likes been stated by others, diffrent dogs respond diffrent to things. All rolling is doing is stating loud and clear your dominant. Many ways that can be done. So I guess for me to say it dont work would be incorrect. It dont always work might be better. Budda was a dog that responded absolutly terrible to harshness. When he was bout a year he did something that really pissed the wife off. She smacked his ass pretty good. Budda growled. So my old tough ass went over and smacked his ass. He growled at me. I smacked his ass one more time and he turned around and growled. That was the last time he ever needed spanked. To him it was like spanking a grown man. It was out of line. He did'nt cower or hold his head down. In fact he did'nt learn not one thing from the situation. But he taught us that it was'nt what he needed. This dog would do anything you asked. He stopped when you said stop, backed up when you said back, got down when you said get down. Anything you wanted from him he would allow, except putting your hands on him. I could smack him till my hands hurt playing, same with kona. But put the wrong tone behind it, smack him just half as hard, and anything you wished to teach just went out the window
Most TMs don't give a care. Or rather, only give a care when its THEIR person speaking and even then only if they WANT to give a care. God forbid that the distraction or problem was their protective instincts kicking in, cause then they don't give a flying f& what you think of what they did. You're much more likely to get a "what?!" sort of reaction out of a TM than a "oh, sorry!!" sort of reaction. Pleasing their human is not a top priority.
