Dandie Dinmont is named after a Character in Sir Walter Scout's, Guy Mannering.

In Sir Walter Scott's novel "Guy Mannering," the character Dandy Dinmont owns a pack of small terriers known as "Dinmont terriers." These dogs are described as being "hardy, rough-coated little black and tan" terriers, and they are said to be excellent at hunting and vermin control. It is possible that the Scottish Terrier was inspired by the fictional Dinmont terriers in the novel, although the breed as we know it today likely evolved from a combination of different terrier breeds over time.
