Don't ask Juice the border collie to run in a straight line. She prefers to weave! Juice can wind her way through 60 poles in 12.3 seconds, the fastest for a dog.

The event is part of a competition called agility, in which dogs race through an obstacle course. The contest is serious, but Juice is just having fun. How can you tell? Says owner Marcus Topps: "She barks through the whole course!"
