Well I think no matter what, there will always be people who agree or disagree with certain techniques. What Cesar does is not actual training though, i.e. sit, stay, down, he teaches people how to be calm, assertive leaders to their dogs which is the root of a vast majority of dog behavioral problems.

I also have to say, he puts the leash/collar up right behind the dog's ears and under their chin, so if they lunge/pull it is not pressing against their pharynx and choking them, and this also controls the dog's head more which is what the purpose of halti and gentle leader is, just without a muzzle strap.

I really like how he emphasizes that a big problem with many dogs too is they are not getting the exercise and/or mental stimulation that they need, another BIG cause of behavioral problems. Especially big strong working type breeds. I think the idea of a walk with a backpack for a big strong dog with excess energy is a very good one. It gives him a purpose, a job to do, something to focus on. Rollerblading with dogs looks fun too .

A lot of the cases he works on are very severe cases with dogs biting people or trying to kill other dogs or just really making life unbearable, and I think he really does well in teaching people how a dog's mind works and that leadership + adequate exercise makes a happy, content dog.

Needless to say, I think he has a lot to offer people and have really enjoyed watching his shows.
