It’s time for the 150th annual Westminster Dog Show. The prestigious canine event kicked off on Jan. 31 with the finals of the agility championship rounds, but there are still two more days of competition leading to the show’s top prize: Best in Show. All of the dogs in competition fit into one of seven categories: sporting, hound, working, terrier, toy, non-sporting or herding. They first compete in Best in Breed, then proceed to Best in Group and finally in the grand prize competition.
