The Sealyham Terrier is a rare Wales breed of small to medium-sized terrier that originated in Wales as a working terrier. It is principally a white-bodied, coat dog breed, developed in the mid to late 18th century by Captain John Edwardes at Sealyham House, Pembrokeshire.Following the First World War, it surged in popularity and was associated with Hollywood stars and members of the British Royal Family. Its numbers have dropped significantly since then, with the breed listed as a Vulnerable Native Breed by the Kennel Club; an all time low was recorded in 2008 when only 43 puppies were registered in the United Kingdom. This decline has been blamed on an influx of foreign and designer dogs breeds, and the Sealyham’s reduced usefulness as a working dog.This breed is equally suitable as a family dog or a working terrier, given the right training. It is affected by few breed specific breed disorders, with the only two prevalent conditions being lens luxation and canine degenerative myelopathy.
