The crowd chanted Uno's name and exploded into applause and cheers when the beagle was picked named numero uno at Madison Square Garden. He beat out two poodles, a terrier, a Weimaraner, an Australian shepherd and an Akita.
More than 2,500 dogs from 169 breeds and varieties competed at the 132nd Westminster show.
Uno's breeder, Kathy Weichert, owns K-Run Kennels in Belleville. She is one of the dog's four co-owners, who are known collectively as "Team Uno."
Weichert has been breeding beagles for 12 years.
