The book is told from the standpoint of a loyal household pet, a dog self described by the first sentence of the story; "My father was a St. Bernard, my mother was a collie, but I am a Presbyterian." The story begins with a description of the dog's life as a puppy and her separation from her mother, which to her was inexplicable. Her puppy and her owner's new child were soon added to her new home. When a fire breaks out in the nursery, the dog risks her life to drag the baby to safety. In the process, her motives are misunderstood and she is cruelly beaten.
