The story centers on a young boy named Joe, whose day takes a distressing turn during a picnic. As the group prepares to depart, Joe realizes that his beloved pet, a "little black and white dog" named Dandy, has vanished. Despite the collaborative efforts of his friends who "helped Joe look for Dandy," the search proves futile. Joe is eventually forced to return home without his companion, filled with anxiety and regret.
Upon arriving home, the atmosphere remains somber. Joe’s father attempts to offer comfort by suggesting, "He may find his way home tomorrow morning," but Joe is unconvinced. His emotional state is captured perfectly by his own words: "It is too far for a little dog like Dandy to find his way home." Joe’s distress is compounded by feelings of guilt, as he laments, "I did not take very good care of him." Throughout the evening, the persistent thought of his "lost dog" prevents him from eating, highlighting the deep emotional bond between the boy and his pet.
The narrative shifts when the telephone rings, providing a sudden glimmer of hope. A stranger calls to report that he has found a "little black and white dog" near the park. Joe quickly confirms the dog is his, identifying him as Dandy. The stranger, who is preparing to leave, is unsure of how to handle the situation, prompting Joe to devise a clever plan.
Joe asks the stranger to take Dandy to "the road near the school," a location he believes Dandy will recognize. However, Joe’s most touching request is to "talk to him first" via the telephone. This moment of connection is poignant; when Joe speaks, Dandy responds with a familiar "Bow-wow, bow-wow." This vocal confirmation serves as a bridge, with the man noting, "Dandy heard you. He is trying to get out of the house." This reassurance empowers the stranger to "start him home," setting the stage for the final act of the journey.
The final part of the story is defined by suspense and relief. Joe spends his time waiting at the window, watching the street with anticipation. His patience is rewarded when he spots "a little dog running down the street." The emotional climax is reached when Joe opens the door and finally holds the "tired little dog" in his arms. The story concludes with a humorous yet tender warning from Joe to Dandy: "If you should get lost again, Dandy... be sure to go to a place where I can telephone you." This resolution underscores the themes of love, responsibility, and the remarkable intuition of a pet finding its way back to its owner.
