The Sealyham Terrier is a short-legged terrier, slightly longer than it is tall. Its body is strong, short-coupled and substantial, allowing for plenty of flexibility. This combination of short legs with a strong and flexible body allows the Sealyham to maneuver in tight quarters. Its weather-resistant coat consists of a soft, dense undercoat and a hard, wiry outer coat. This is a keen, alert and determined breed and should look the part.

One of the calmer terriers, the Sealyham is nonetheless ready for action, always happy to investigate, dig or give chase. It is often aggressive toward other dogs or pets. It is a well-mannered house dog but needs some daily exercise. It is reserved with strangers, but devoted to its family. It is stubborn and independent. It digs and barks.


The Sealyham was developed in Wales in the middle of the 19th century by Captain John Edwards. He crossed the Dandie Dinmont Terrier, West Highland White Terrier, Welsh Corgi, Wirehaired Fox Terrier and the Bull Terrier to produce the Sealyham we know today. The dogs were developed to go to ground after badger, fox and otter. The white coat helped the hunters distinguish the dog from the pray. The Sealyham Terrier was recognized by the AKC in 1911, and the American Sealyham Terrier Club was founded in 1913.
