Sealyham Terrier Information

Sealyham TerrierThe Sealyham Terrier is in a unique size category at 20-25 pounds: not big enough to be considered a medium breed but much larger than what you’d think of as a small dog. He is strong, muscular and agile, despite standing low to the ground. The Sealyham also sports a unique-looking white coat with striking facial fur.

Over time the popularity of the Sealyham has waned, which is a shame because he is an outgoing, cute, funny and affectionate dog with a wicked sense of humor. They are excellent watchdogs and have been used a therapy dogs due to their friendly nature.
