Crawford and the early founders of the Jack Russell Terrier Club put a lot of thought into structuring the JRTCA so that work remained front and center.Towards that end, the club decided that its highest award — the “Bronze Medallion” — would not go to show dogs, but to working dogs that had demonstrated their ability in the field by working at least three of six types of American quarry — red fox, gray fox, raccoon, groundhog, opossum, or badger in front of a JRTCA-certified field judge.
