February 9-11, 2020 - The 144th Annual Westminster Kennel Club Dog Show takes place at Madison Square Garden in New York.
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.
