The Humane Society of Missouri is part of a joint effort to create the country’s first dog-fighting database. I volunteered to take some photographs for them, and in June the New York Times picked up the story. According to the Times, the Combined DNA Index System is similar to the FBI’s digital archive containing the DNA profiles of criminal offenders. Scientists say that by swabbing the inner cheek of a dog, they will be able to determine whether the animal comes from one of several known dog-fighting bloodlines.
