2019 Westminster Dog Show: Top Highlights, Photos and Twitter Reaction

The Westminster Dog Show will conclude Tuesday night in New York City with the awarding of the heralded "Best in Show" honor at Madison Square Garden.

The American Kennel Club classifies various dog breeds into seven categories, including herding, hound, working, sporting, non-sporting, toy and terrier group.

After the dogs compete for best-in-breed titles, the winners advance to the Westminster final Tuesday evening.

Four group winners were announced Monday, including Baby Lars of the herding group, Burns of the hound Group, Colton of the non-sporting group and Bono of the toy group. 

After the winners are named in the sporting, working and terrier groups Tuesday night, the Best in Show competition will play out and the top honor will be awarded.

The Best in Show is clearly the highlight of the competition, but the most enjoyable event from the spectator's perspective may be the Masters Agility Championship.

In that event, dogs weave their way through obstacles. In addition to showing how well the dogs move and demonstrate their speed, it also shows the ability to handle one challenge after another.

The Westminster Dog Show held its first competition in 1877. While there is no prize money awarded to the winners (groups and best in show), the breeding rights fees can be the reward later down the line.

Last year's winner was Flynn, a Bichon Frise, who has since retired from competition.
