Physical Characteristics:

The Sealyham Terrier is low to the ground with short legs, a long body, and a long and domed skull. There is a slight indent between the brows and running into the muzzle. The coat is white sometimes with lemon or badger color added and sheds very little. The coat is kept long on the legs, over the brows and muzzle. The tail is docked where permitted. 

History of the Breed:

The Sealyham Terrier was developed by crossing the Dandie Dinmont Terrier, the Corgi, West Highland White Terriers, Wirehaired Fox and Bull Terriers. This breed was developed by Captain John Edwards at Sealyham House, Wales, in the mid 19th Century. He desired to produce a breed with a white coat that was easily distinguished in the field that was strong and suited for going to ground to hunt fox, badgers, and otters. This dog became popular with the Hollywood elite after World War I, and was one of the most popular terriers in the English-speaking world; however, registrations have dropped to levels bordering on near extinction in recent times. 


The Sealyham Terrier is a happy, cheerful breed that is also sturdy and tenacious. They are not as boisterous as some of the other terrier breeds. If properly socialized, they can be friends with cats and other non-canine pets. Great with children and devoted pets. 

  • Best suited for: Almost any family. Does well in the country or in the city. Versatile. Good for allergy sufferers. 
  • Preferred living conditions: This dog prefers to be an active part of the family and loves having other canine housemates.

Care and Health:

  • Grooming requirements: This coat sheds minimally but requires regular brushing to prevent mats. Stripping is required. 
  • Exercise needs: Daily walk.
  • Life expectancy: 15+ years.
  • Health concerns: Generally healthy with a few eye problems detected in some lines.
