The Crufts dog show went down in Birmingham, England this weekend. It's the largest annual dog show in the world . . . with 21,000 dogs competing this year. A seven-year-old Lhasa Apso named Elizabeth ended up winning Best in Show. But the best moment of the weekend was when a five-year-old mixed breed named Libby stopped in the middle of her agility routine . . . and DROPPED A DEUCE in the middle of the arena. She was immediately disqualified, but still got a round of applause from the crowd.
