For dog-lovers, there's nothing like Westminster, with 2,500 competitors and 173 breeds, like Chanel, the Whippet, and CJ the Doberman, reports CBS News anchor Katie Couric.
But there can only be one top dog, and this year it was.
It's her biggest win yet.
At four years old, Sadie's already won 112 titles.
She's the first Triple Crown winner, having won the National Dog Show in November and the American Kennel Club Show a month later.
And she kept her poise even as animal-rights protesters tried to crash the party, before they were arrested.
Trophies and ribbons are nice. But for Sadie, the real reward was her favorite treat - chicken.
