The bichon frise, named Flynn, beat out nearly 3,000 four-legged competitors to take home the top title.
The next stop for Flynn, only the second bichon frise in history to win at Westminster, is retirement, McFadden said.

Flynn, 5, came out on top over Ty the giant schnauzer, Biggie the pug, Bean the Sussex spaniel, Lucy the borzoi, Slick the border collie and Winston the Norfolk terrier in the final round, according to ESPN.
The two-day Westminster Kennel Club Dog Show drew challengers from 50 states and 16 other countries, including Canada , Mexico, Japan, Russia, Australia and China, the Westminster Kennel Club said in a statement.
Flynn stood out as the "perfect example of his breed," according to Gail Miller Bisher, communications director for the Westminster Kennel Club.
McFadden explained what goes into creating a winning look for Flynn, whose given name is GCHP CH Belle Creek's All I Care About Is Love.
