Effort Uses Dogs’ DNA to Track Their Abusers

[douglas9]

ST. LOUIS — Scientists and animal rights advocates have enlisted DNA evidence to do for man’s best friend what the judicial system has long done for human crime victims. They have created the country’s first dog-fighting DNA database, which they say will help criminal investigators piece together an abused animal’s history by establishing ties among breeders, owners, pit operators and the animals themselves.

Called the Canine Codis, or Combined DNA Index System, the database is similar to the Federal Bureau of Investigation’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.

“People are not generally going to the pound and buying pit bulls to fight — these dogs are from established bloodlines,” said Tim Rickey, senior director of field investigations and response for the American Society for the Prevention of Cruelty to Animals. “And if a suspected dog fighter’s animal matches one of those bloodlines, that would be a key piece of evidence.”

The database, a joint effort by the A.S.P.C.A., the Louisiana S.P.C.A., the Humane Society of Missouri and researchers at the Veterinary Genetics Laboratory at the University of California, Davis, was developed during an investigation last July that resulted in 26 arrests and the seizure of more than 400 dogs. The investigation, which stretched across seven states, from Iowa to Texas, resulted in the largest dog-fighting raid in United States history, the authorities said.
