If there is cock fighting, then there is dog fighting. I knew dog fighting already existed. I knew there are wicked people who train dogs to fight. Which is very bad and unhuman act to dogs. I remember when I watched Imbestigador here in Philippines. It featured dog fighting. Those dogs have rights, even if they're animals.
