The Houston World Series of Dog Shows takes place in Houston’s state-of-the-art NRG Center. It is a cluster show, meaning it is actually several separate shows, held over consecutive days. Beginning Wednesday, visitors can catch the more than 30 independent breed specialty competitions, as well as the Houston Hound, Working Dog and All-Terrier shows — don’t miss the chance to chat with owners/handlers as they prepare their show dogs in the Crating and Grooming area. Thursday offers an all-specialty group of shows with only Conformation (Breed Judging) competitions that end with a “Best in Show” award. Friday, Saturday and Sunday each culminate with a “Best of Show” winner, chosen from finalists among the seven variety groups with more than 150 different breeds represented. The four “Best in Show” winners may or may not be the same dog.
