Rango, the dog

There was a dog. Middle size, shiny black coat, black toungue and cute and kind eyes. She was fluffy, looking  like a little bear. Everybody wanted to hug that dog, and she paid the same interest to people. She was happy to see anybody at any time. Kids loved  that dog, and could spend the whole day playing with her. When it was time for her to have puppies, they were just as cute as she, and everybody loved them just as much.
One day a man walked that dog in the neighborhood. She would  get a bit in front, like other dogs often do, and did a little snooping around. When they approximated to the curve, a man saw a big, strong dog, that would sit close to the owner without a muzzle and the leash. He shouted out to the woman next to the dog to hold it while he with his little dog would pass by  them, to which woman just indifferently looked and performed no actions about what she was asked of. A man called his dog to come closer to him, and the dog did gladly obey him, but on the way to him, the big dog took off  and started running on a little dog.
The big dog were big enough to knock over a man. By running up on the little dog, it was barking loud, showing its big white teeth, and the little dog just stopped running, and simply submitted to its destiny.
It all happened  fast. While the man was running towards them, the big dog got on the little one, grabbed her by the back with its big sharp teeth, and started to tear her up like an old shoe.  Running up fast, showing not a sign of fear, a man got on the big dog, and started to choke it. The woman began to yell, trying to make a man let her dog go, but the man wouldn't stop. He continued choking it, until it loosened the grip, and let the little dog run away. The big dog then was barely breathing, when the man looked over the woman again, and ask if she wants her dog dead or alive. In a second, he let the dog go, but now, his eyes were red, full of anger, and he looked ready to smash anything that would get on his way. The lady got scared, took her big animal, and they left. The little dog got spot in the shadow, leaned back against the fence, and licked her bleeding wounds moaning.
