whats the best way to cattle break a dog

I like to e-collar stock break my dogs. I send a newby out around cattle, or whatever I want to break for, and never say a word to the dog. I may not even get out of the truck. My reason for this is that I want the dog to treat that stock the same no matter where I am. If I am across the ranch from the dog I dont want that dog to get the idea that this is a good time to chase something. I gave a dog back to a buddy one time that I had broke the old fasioned way. Told him he did not have to worry about that dog ever chasing stock brcause he was totally broke, which he was for me. After an episode of cow chasing and mag-light therapy the dog was stock broke for him too. Dogs get bright ideas just like people do!
