Jack Russell breeders resisted entry into the AKC for many years because the AKC wanted a specific standard for size, coat, etc. To true loyalists of the breed this was unnaceptable because they believed that breeding for specific traits of size, coat and confirmation would destroy the one trait that lovers of the Jack Russell treasure most...personality and hunting instinct. In order to accommodate the different sizes, the AKC first accepted the longer legged Jacks (between 12-15") as Parson Russell Terriers and the smaller Russell Terriers (under 12"). The JRTCA accepts Jack Russells of all sizes and still promotes the original characteristics of the breed.
