One of the really fast game terriers, they were bred for otter, fox, badger, rabbits, and rats. They are very fast and agile. The breed was originally called Rothbury Terrier, but a man named Bedlington bred two of those calling his a Bedlington Terrier, and made it stick.
This is one of the terriers that can live with a cat without troubles. They will chase game outside but seem calm and relaxed inside to the point of being lazy. Their coat is also softer than other terriers, a nice representation of its nature as well. This is a quiet dog, but will not allow itself to be bullied.
