I’d rather see them (humans) fight to the death, until one is left standing. Then bring in the next batch. When they aren’t fighting keep them in cages only large enough for them to squat. They can have food, but only enough to stay alive. Maybe then, dog fighting would stop. If they cause too much of a commotion, clip their vocal cords. Life in prison, too easy of a punishment. A punishment should fit the crime.
