What is dog fighting?

It is when a person decides to take in dogs( usually pitbulls) and test them to see their fighting ability. If they believe that they will not be good at fighting then they kill them in one of many torturous ways. If they think they are "Game" enough they keep them and train them how to kill. Then sometimes the dogs are not fed so that they will be more able to kill. They either die or win. If they lose they will be killed by the other dog and if not killed by the people.
