Love him or hate him, think he is right, wrong or are indifferent to his techniques, the way I see it CM is not a dog trainer, a statement he's made again and again. He's more or a self-help guru, a self described dog psychologist if you like. He likes to point out that he trains people, and from what I've seen, it is the people who need training. And so he spends a lot more time talking about changing human behavior than he does about training dogs. IMO, what viewers see of him on t.v. is usually done for ratings, not so much of what actually goes on behind the scenes. Also, he's usually called to work with dogs that are on their way out, either because their owners are incompetent in handling them or the dog has been deemed a threat to society and it's up to CM to try to rehabilitate it. And so t.v. drama unfolds, neatly packaged into an hour of entertainment for the masses. Reality t.v. is still just t.v. and I take it with a grain of salt.
While CM provides some basic how-to advice on dealing with dogs, his handling methods, (which I suspect to CM might be secondary to his overall philosophy), are what elicits most of the hatred directed at him, resulting in his philosophy being somewhat overlooked. Which is too bad. I've read a few of his books, and have enjoyed them, but they certainly are not 'tricks to train your dog' type of books. Nevertheless, I really like his emphasis on the necessity of exercising your dog, not anthropomorphizing your dog, the need for balance, and giving direction via calm-assertive leadership. Also the whole 'no touch, no talk, no eye contact' while introducing reactive dogs to strangers is spot on in it's advice.
However, personally I do not believe in flipping dogs over in hopes of making them submit, and showing them you are the "alpha". Plus I'd like to see him (or anyone for that matter) flip over a strange aggressive 150+ lbs mastiff and show how well this technique works in rehabilitating the dog. I doubt that even CM, who is known for such tactics, would attempt it. Through the years I've watched many of the episodes, and usually CM is able to make a breakthrough with the dog after only a few minutes upon meeting it, the dog submits and relaxes, going along with what is asked of it. I've only seen one episode where it took CM something like twenty minutes to approach a dog, and that dog was 130 lbs and aggressive, there was no flipping him over, no "kicking" it to snap it out of it's zone, etc. So I am pretty sure size/strength/intensity of dog plays into how CM handles him, just as much as what he is willing to do for ratings.
