Vick's dogs prove each dog is an individual

"The Vick dogs showed that even under those circumstances many of them still did not prefer to fight, and even when they did, the simple fact that they were pit bulls did not guarantee that they would be good at it. The truth, in the end, is that each dog, like each person, is an individual. If the Vick dogs proved nothing else to the world, this would be a significant advance."
