ジャック・ラッセル・テリア
In the late 1990s, the American Kennel Club explored the possibility of recognising the Jack Russell Terrier. This move was opposed by the Jack Russell Terrier Club of America as they did not want the breed to lose its essential working characteristics. The Jack Russell Terrier Breeders Association formed and petitioned the AKC; the breed's admission was granted in 2001. Under the AKC-recognised standard, the size of the breed was narrowed from the previous club's standard, and the name of the AKC-recognised Jack Russell Terrier was changed to Parson Russell Terrier, with the Jack Russell Terrier Breeders Association renamed to the Parson Russell Terrier Association of America.
