I think Caesar has a great way of approaching the issues he encounters on his show. I've watched a lot of his episodes and I've never seen anything that made me question his methods.
When it comes down to it I think he has a great understanding of the primal needs of dogs and how to correct common day issues by addressing those needs.
Here is an episode on puppy mills that you can watch on Hulu. It shows some of the more patient techniques that Ceasar uses which don't involve the "Alpha" presence.
