Winners from each breed were then put forward into the best of group competitions, with those seven perfect pooches competing for Best in Show.
The eventual champion was Trumpet the Bloodhound who became the first of his breed to win the grand prize in the history of the event – the second-oldest continuous sporting event in the USA after the Kentucky Derby.
To do so he defeated a French Bulldog, a German Shepherd, a Maltese, an English setter, a Samoyed and a Lakeland terrier.
And after his win he joined owner Heather Helmer on a trip to the top of the Empire State Building to take in the view and get some pictures taken.
