This Welsh breed was named for the family home of its creator Captain John Edwardes.  His spunky earth terrier was bred for the courage needed to tackle vermin that intimidated other dogs, such as badgers, fox, and weasels.  The exact mixture of breeds he used to create the Sealyham is not known.  Some say it included Corgis, Bassets, Dandie Dinmonts, Bull Terriers, and West Highland White Terriers.  Whatever he used, the result was a superb hunter.  The Sealyham entered the English show world in 1910 and was recognized by the American Kennel Club (AKC) the following year.
