This was a dog training video I created back in 2009. I am a big believer in the idea that you should never hit a dog as a part of training. Apart from the morality of such an action, it is simply not effective. Dogs don't understand why you are hitting them. It will only make them hand shy and neurotic. The clicker training works so much better.
Dino was a good dog. He loved doing "tricks" as it gave him a sense of purpose. Dogs are like humans in that they do not do on welfare. A dog need to "work" for his food. Dino's job was to do a trick before he was fed.
