More than 2,500 dogs descend on New York's Madison Square Garden for the ultimate test of breeding, training and showmanship. After hours of deliberation, the judges narrow the broad field down to seven finalists, one of which will win the most prestigious canine award: Best in Show. Host Lester Holt and dog expert David Frei provide analysis and commentary, while Debbye Turner conducts interviews with many of the top dogs and their humans.
