And then there was this one guy, Sam, who used to work with police dogs and he had no time for any of that shit at all. "If the dog thinks you are the boss," Sam said, "you will be fine. You pay attention to the dog, you feed the dog, you exercise the dog, you own the dog, it’s your dog. However, if the dog thinks you are weak, it will fuck with you. Dogs are not cosy. Dogs are dogs. They are animals. They need clear hierarchies or they get confused and when they’re confused they piss on things, bite things, and mate with things until they get less confused. That’s all. That’s what it is. There’s just you and the dog and one of you is on top." And then he looked out of the screen and I swear to you he was talking only to me, and he said: "Actually, it’s not all that different with people." And I knew that he was right.
