Actually, cesar uses out dated methods anyway. The dominance theory has been disproven, as it has also been proven that reinforcing good behaviours and ignoring or interupting bad behaviours works. Now i will say, for the method cesar uses, he is actually good at the method and has great timing which is very important if you want to use punishment to train. And the whole stayig calm thing, and not worrying about what your dog did yesterday or even 5 minutes ago but living in the moment.
But even with him, on the show I see dogs displaying common stress signals like panting (not after exercising or on a hot day), yawning, lip licking, uncertain body posture etc. Or just dogs that are shut down. A lot of the 'red zone' dogs I see him with? Pfft give me a bag of treats, my clicker (or even my voice), and I will have the dog trained in the same time as cesar (keep in mind he takes longer then half an hour to train a dog. When filming they have to edit a lot of stuff out). He gets bit a lot. A good trainer rarely gets bit because they understand dogs body posture and behavior, and know how to not get bit. Also I don't have the link any more, but I have read a few links talking about dogs he has trained, going back to their old ways after a few months.
No reason to use physical corrections when positive methods work better in most cases and also give you a better bond with your dog. I am not a professional dog trainer (yet) but I have done a lot of research, watched dvds, read books, gone all over the internet and also researched cesar and his methods. Also trained my two dogs, one who had bad aggression problems about a year ago, and also done some training with other peoples dogs. I have probably just about given myself as much education as he has given himself, as he never actually recieved any education on dog training, just went straight into the career. Not that that can't work well, it's just he isn't keeping up his self education and staying with the times on dog training.
