The Dog Whisperer is on Sky 3 (freeview) everyday at 6pm. The guy is called Cesar Millan and he seems very effective as he deals with aggressive dogs mostly. Watching him clicking his fingers and watching an agressive pit-bull spring off the couch and becoming submissive is exciting viewing (if you are into dogs). Excepting that this is TV and designed to look good; the guy is inspirational! Certainly his philosophy of using calm, assertive energy with your dog is sound. I'm not sure how popular he is in this country, he has caused some controversy, I suspect because we are a bit soppy with our dogs! Just about all nationally approved pet training uses positive reinforcement and Cesar uses some negative reinforcement and coercives. If the owners are using prong-collars or e-collars, so does Cesar and we sensitive Brits don't like that. But personally, I think he is brilliant because he uses the same discipline methods as dogs use, a short sharp distraction to jolt the dog out of the wrong behaviour in a calm and assertive manner. The dogs he treats (which are extreme) seem to just give in to his will without a fight. He doesn't hurt any dogs even a little bit but he doesn't leap about cramming tit-bits in their mouths either!

Its certainly worth a watch
