The story
The number of Kerry Blue Terriers increased dramatically in the Dublin area as the breed gained admirers in the early 1920s. On St. Patrick's Day 1921, a conformation dog show was organized which included other breeds, in opposition to The Kennel Club of the UK. The popularity of the show was the catalyst that led to the formation of the Irish Kennel Club. The first meeting was held on January 20, 1922.
