Regular Smart Dog Blog readers know that there is an awful lot about which Cesar and I disagree. Here's a news video explaining why.
Dog training isn't an art, it's not about restoring balance, and it's not about discipline. It's simply about modifying behavior. It's science through and through.
When watching the video, turn the volume down and simply look at the dogs. He hasn't restored calm and balanced. They are stressed and shut down. A stressed dog is more likely to bite. A dog who has shut down (also called "learned helplessness") is very likely to bite without warning. Clearly, Millan's methods are something you don't want to try at home.
If you need help with your dog, look for someone who uses positive reinforcement methods (clicker training, for example). Check out Karen Pryor's Clickertraining website, the Association for Pet Dog Trainers, and the Certification Council for Professional Dog Trainers. Or contact me and I can help you find a qualified positive reinforcement trainer in your area.
