Sealyham Terrier Resource

Sealyham Terrier

A one-man creation, the Sealyham is named for the Welsh estate of Captain John Edwardes, who developed the tough white terriers to go after badger, otter and fox. The dogs became well known for their working ability, and in 1908 a breed club was formed and a standard drawn up. Today’s Sealyham is most often a companion, but when given the chance it’s ready and willing to go to work. More outgoing and friendly than many terriers, this dog is still an excellent watchdog, with a bark that’s impressive in its loudness. It stands about 10.5 inches at the withers and weighs 23 to 24 pounds, with females slightly less. The wiry, weather-resistant coat is all white or white with lemon, tan or badger markings on the head and ears. It doesn’t shed much, but it should be combed about three times a week to remove dead hair and prevent mats. The Sealy has a moderate activity level and fits well into any size home. It’ll enjoy a couple of daily walks and playtimes. Sealyhams learn quickly with firm, fair discipline, but you can count on them to add a personal spin to obedience commands.
