As I recall at the begining of ever Cesar Milan show it says "please do not attempt what you see at home".
Yes, of course they say that. These kinds of forceful, intimidating, coersive "methods" put a dog into fight or flight mode. Their autonomic nervous system goes into gear and their cortex takes a back seat. Adrenaline rises, heart rate and blood pressure increase. Hormones responsible for an animal's survival flood the brain and rest of the central nervous system. Fight or rather flight (fight, since fight is not an option) is what fills the dog and everything else drops off. No thinking or reasoning is possible. The dog needs all of his energy to escape. If this were not so, no animal could survive, reproduce and evolve. And we all know how successful dogs have been. Well, he can't escape so what do you have left?
This is one reason why these so called "methods" are so dangerous. Not only are they grossly unfair and completely not taking into account a dog's nature or cognitive ability, they put humans at danger.
Sure, it appears that many behaviors are stopped. And they are for a time. But how? The dog can not escape. Then dog usually is prevented from attacking because most of the time the human (Cesar) is stronger and more scary. So the dog gives up and falls into what is called "learned helplessness." He shuts down. He can't learn when he's in this shut down state. AND he can't learn anything when his physiological/central nervous system is getting ready to flee from or fight with his attacker.
This is why there are regressions with the dogs Cesar Milan trains. They ARE dogs that show stress signs to anyone who really knows dogs.
Cesar Milan does not know behavior. Obsessing over pack theory is irrelevant with a human/dog relationship. And Richling is even worse. He's really not taking any dog behavior into account. NONE.
