"Cesar Millan's methods are based on flooding and punishment. The results, though immediate, will be only transitory. His methods are misguided, outmoded, in some cases dangerous, and often inhumane. You would not want to be a dog under his sphere of influence. The sad thing is that the public does not recognize the error of his ways. My college thinks it is a travesty. We've written to National Geographic Channel and told them they have put dog training back 20 years."
