- The Westminster Dog Show debuted in 1877

February 15-16, 2016 - The 140th Annual Westminster Kennel Club Dog Show is scheduled to take place.
The show is "benched," meaning the dogs must be on public display to ticket holders throughout the competition.
Dogs are invited to compete based on strict entry requirements, including how many other dogs they've defeated in breed competitions. Non-invited dogs can also compete if they have won a certain number of major dog show awards.
Breeds are categorized into groups: Sporting, Hound, Working, Terrier, Toy, Non-Sporting and Herding.
The dogs compete for Best in Breed, then move up to Best in Group, then compete for the grand prize of Best in Show.
192 dog breeds and varieties are eligible to enter.
2,711 dogs entered the 2015 Show.
Terriers have won the most Best in Show awards -- 46 as of 2015.
Forty-seven breed varieties have won Best in Show awards, as of 2015.
Seven dogs have won more than one Best in Show. The most recent was an English springer spaniel named Chinoe's Adamant James, who won in 1971 and 1972.
