NEW YORK (AP) — When the Westminster Kennel Club dog show added an agility competition a decade ago, it opened U.S. dogdom’s most elite door to mixed breeds for the first time since the late 1800s.

But purebreds won every year — until Saturday, when a border collie-papillion mix aptly named Nimble outran and outmaneuvered 50 other finalists to seize the trophy and plant a flag for blended-breed dogs everywhere.

“She just tries hard, and she’s a wonderful dog,” handler Cynthia Hornor told The Associated Press this week.

Just about a foot (30.5 cm) tall, Nimble powered through an obstacle course of jumps, tunnels, ramps and other features like a furry, black-and-white, well-targeted torpedo to cheers from the crowd in the agility finals.

Victory goes to the fastest canine, with penalties for any goofs in clearing the obstacles. Handlers run alongside to signal their dogs where to go. A time under 30 seconds is notable.
