Summary

The Sealyham Terrier owes its name to the Sealyham estate, in Pembrokeshire (Wales), where Captain John Edwardes bred, over 40 years in the 19th century, an ideal white terrier for hunting otter, badger, and rats in water and on land. He probably crossed Basset Hound, Bull Terrier, Fox Terrier, West Highland White, and Dandie Dinmont to obtain this robust, low-slung breed with excellent scenting ability and incredible tenacity. Today it is one of the rarest breeds in Great Britain.

Temperament & Personality

The Sealyham is spirited, courageous, and with a sense of humor that delights its owners. Unlike many terriers, it has a calmer and more balanced temperament — less hyperactive and more willing to relax at home. It can be reserved or suspicious of strangers and does not always get along with other dogs. Its dark playful aura and quiet personality make it a highly appreciated companion for those who know it.
