Many Mini Rex rabbit shows are either local or national. Some shows are not sponsored by the American Rabbit Breeders Association (ARBA), but rather by local or state Breeders Associations. Some Mini Rex shows are sanctioned by local show "designators" who set up and organize the event. Rabbit's are judged by national judges and the winners are announced at the end of judging. Rabbit shows are divided by class (color, age, and gender) and announced three times; If there are not enough show entries on the table or not enough show up, the class can be canceled. Rabbits can win a "leg" at sanctioned shows, that are noted as a winning, these can be won by having 5 rabbits or more in a class with 3 or more exhibitors. the "legs" can be classified by BIS (best in show) BOB (best of breed) BOS (best opposite sex) BOV (best of variety) BOSV (best opposite sex of variety)
