About the Sealyham Terrier

The Sealyham Terrier is a rare and charming Welsh breed originally developed in the mid-1800s by Captain John Edwardes on his Sealyham estate in Pembrokeshire, Wales. These small, sturdy terriers were bred to be fearless hunters of otters, foxes, and badgers. With their distinctive white coat, powerful jaws, and endearing whiskered face, Sealyhams have a look that is both tough and adorable.
