Sealyham Terrier History

Breed History

The Sealyham Terrier originates from Sealyham, Wales, where, between 1850 and 1891, Captain John Edwards developed the strain from what may have been crosses between Corgis, various terriers, and possibly even some hounds....

Edwards created his breed with a keen eye to bravery, and eventually his dogs became renowned for hunting otter, fox and badger. The Sealyham's first appearance at show was in October 1903 in Haverfordwest, Wales, where five years later the Sealyham Terrier Club of Haverfordwest formed and created the original breed standard. In October of 1910, the breed appeared in its first championship show at the English Kennel Show, and the Kennel Club officially recognized it in March of the following year. Soon thereafter, in 1911, the Sealyham Terrier was recognized by the American Kennel Club, only shortly after importation. The popularity of the breed at show has been fairly constant since its American debut in September 1911 in San Mateo, California. The American Sealyham Terrier club was established May 15, 1913. The Sealyham Terrier has won Best in Show at Westminster four times. Though fewer then 100 Sealyhams are registered with the AKC each year, the breed does boast some famous owners. Gary Cooper, Humphrey Bogart, Cary Grant and Alfred Hitchcock all owned Sealyham Terriers; in fact, Hitchcocks dogs made cameo appearances in The Birds and Suspicion.
