And while we’re clearing things up, his last name is Millan. 
I’ve only seen the show a couple of times, but one of the times I watched it with my father the retired veterinarian (thirty-seven years of small animal practice).
He endorsed the idea of lots of exercise whole-heartedly, especially for big dogs. And I used to work for my dad, and I never saw a dog he couldn’t handle, and that includes animals crazed with fear and pain. They might be ferocious terrors at home, but they were apologetic tail-waggers five minutes after he got them on the exam table. And he never struck a dog in his life.
But he had two of the same, major advantages that Cesar Millan has:[ul][li]The unshakeably calm assumption that he was in charge, and that the dog’s role in life was to obey, and [/li][li]the dog had no idea what to expect from him, and he knew exactly what to expect from the dog. And decades of practice in dealing with it.[/ul]I am under no illusions that every dog can be tamed in twenty-four minutes, and obviously there is a lot of training cut out. And I did actually see Cesar (and my dad) get bit. But neither of them reacted with anger. Just part of the job, and they got on with it. [/li]
My $.02 worth, and perhaps skewed by my admiration of my dad.

Ok 40 hours was an exaggeration, and in fact most of my feelings come from his book rather than the show. But he does recommend a very large investment of time from dog owners. If I am remembering right he talks about taking the dogs he is working with and running them for a few hours in the AM and again in the PM, everyday. I think that is a little unreasonable for most owners.
I have Aussies and they are at the top end of the energy and intelligence scale. With the fostering I do for Aussie Rescue (22 foster dogs in the last 2 years!) I feel that the most important thing is quality over quantity. You can spend 8 hours a day running your dog, and it will be worn out. But mostly I try to spend some time making my dogs run and then give them something to do to work the little beans rattling around in their heads. Some days that doesn’t even happen, there are times that my high energy dogs have to hang out in thier crates more than they would like. Yet they are well adjusted (mostly) dogs.
I agree that four hours a day would be unreasonable. However, that is not what he recommends.
It is indeed Cesar MILLAN.
He was the only one able to contorl Eric Cartman. 
I’d also like to point out that every time they show him doing something risky, like an alpha roll or some other direct confrontation with an aggressive dog, they also have a voiceover or text on the screen saying that dog owners should not attempt these things themselves. He is a professional and knows what he is doing. The owners are lucky to have him there to do it–this does not mean he’s saying all the yokels at home should be doing the same things in their situations.
I enjoy his show and think that a lot of what he says makes sense. I like that he has no qualms about challenging the owners’ perceptions. Dogs aren’t little people, as someone mentioned upthread. In my opinion, a lot of issues people have with their dogs arise because they’re not treating them like dogs. I’m not a pet parent. I’m a dog owner.
As for the accusations of abuse? I have a hard time believing it and think that if it were true, someone he’s worked with would have come forward by now. I think he has a gift and truly has a great deal of admiration and love for dogs. We’ve incorporated some of his techniques in our household (especially after bringing home a four-month-old yellow lab pup and introducing him to our 10-year-old female chow mix) and I’ve had to change my way of thinking about many things.
Hell, I was more shocked by our obedience trainer introducing the pinch collar on our lab than by anything I’ve ever seen on Cesar’s show. But you know what? That pinch collar works. Our lab is learning fairly quickly and while there are still a lot of issues we’ll be working on, he’s come a long way (and has “mastered the walk”).
For the record, when asked about Cesar, our trainer said, “He doesn’t get those dogs under control in 20 minutes.” Well, duh. It’s edited for television. I suspect some of those shows would be several hours long, otherwise.
If the end result is a calm, well-balanced and well-behaved dog, that’s what’s important.
