The annual dog show is the second-oldest continuous sporting event in the United States. The dogs first compete for Best in Breed, then move up to Best in Group, then compete for the grand prize of Best in Show.

This year's show featured 209 breeds and 3,500 dogs, according to the Westminster Kennel Club.
