Mean Rottweiler Neighbor Dog

I have a mean rottweiler dog in my neighborhood. Unfortunately, this rottweiler is with some scary humans. I am guessing that he is being trained for dog fighting. They make him wear a metal spiked looking chain around his body. Everytime he spots me, he goes crazy! This rottweiler dog is completely mental. He barks, growls and salivates from his mouth. All the time, straining on his chain to get me. My mommy says that human males that train dogs to be mean are trying to compensate for their extremely small thingymajigs. When that rottweiler was a puppy he had potential to be something. Now he is just a status symbol for some ignorant human dork. I think all dogs being treated like that should call the police and report it. Humans like that should be locked up in the pound.
