NEW YORK — A beagle wagging her tail a mile a minute has become America’s top dog.

Miss P pulled an upset, winning Best in Show Tuesday night in the 139th Westminster Kennel Club dog show at Madison Square Garden.

The 4-year-old dog is related to Uno, who in 2008 became the only other beagle to win at the nation’s most prominent dog show.

Miss P beat out Matisse, a Portguese water dog that was the top-winning male in show dog history. Judge David Merriam also picked her in the best-of-seven final ring over an old English sheepdog that clearly was the crowd favorite, a standard poodle, a shih tzu, an English springer spaniel and a Skye terrier.

The Skye finished second.
