The annual competition features 2,882 dogs from all 50 states, and 16 other countries including Canada, Mexico, Japan, Russia, Australia and China.
Individual breeds are being judged and the winners of each move on to the group competitions at night.
Dogs are divided into seven groups for the evening events – hound, toy, nonsporting, herding, working, sporting and terrier.
For the first time since 2006, no new breeds will show on the green carpet.
