The United Kennel Club (or UKC) is the second oldest all-breed registry of purebred dog pedigrees in the United States and the second largest in the world. According to the website, the club records 250,000 registrations annually. The UKC is not part of the International Canine Organisation, Fédération Cynologique Internationale, as most other countries' kennel clubs are. The UKC was founded by Chauncey Z. Bennett in 1898. The UKC states that Bennett formed the club in order to provide a registry for working dogs as opposed to the American Kennel Club's emphasis on dog conformation shows. Some UKC detractors claim that the club was originally formed so that the founder could register his American Pit Bull Terrier, Bennett's Ring. - Source: Wikipedia
