Cairn terriers are small—but their fun personalities can easily fill up the big screen! Right off the bat, readers will meet Terry, the little cairn terrier who played Toto in the 1939 classic movie The Wizard of Oz. Toto became one of Hollywood's most famous dogs because of the loyalty, courage, and intelligence that Terry showed on screen—traits that any cairn terrier owner would instantly recognize. Where did these qualities come from? Perhaps they can be traced back to the cairn terrier's ancestors, who worked on farms in the Highlands of Scotland hundreds of years ago. These working dogs were bred for loyalty, intelligence, and bravery so they could help farmers hunt down farm pests like rats and weasels. A narrative treat for dog lovers, Cairn Terrier: Hero of Oz covers the breed's history and its relationship to the animal's current size, physical and mental characteristics, and suitability as a pet.
