Bob and his dog Rowdy are inseparable companions, but, owing to Rowdy's propensity for mischief, such as wiping his muddy paws upon the bed, tearing up a new Spring hat belonging to Bob's sister and generally creating havoc throughout the house, Bob's mother decide to get rid of him. While Bob is at school she gives Rowdy to the milkman, who carries him off in triumph. Bob returns from school and his first thought is of his pet. He calls and whistles, but Rowdy does not respond. After a vain search through the house he tries the street. Here he is informed of his mother's transaction with the milkman by his little friend next door. Bob at once prepares to trail his four-footed pal. From a bill in the kitchen he learns the milkman's address, then breaking open his savings bank and taking his savings, he starts on his journey. He finally locates the milkman's house and after a few minutes of whistling and calling, Rowdy rushes pell mell into his arms, trailing a broken rope as evidence of his struggle in answer to his master's call. Bob now decides to lay his course to the wild and woolly west. Nobody loves him and his dog so they might as well go away. He stops at a small post office and writes a postal card to his parents, saying that he and Rowdy are on their way out west to catch bears for the zoo and bids them farewell. Not wishing to cause them unnecessary worry, he sends the card by special delivery and trudges on his way. Meantime the household has been thrown into an uproar over Bob's disappearance and a thorough search fails to uncover any clew. Suddenly a boy delivers the postal card and taking the postmark as a clew, his father and mother hurry away in their automobile. Arriving at the post office they learn that Bob had been there and hurry away in the direction he was last seen going. Bob, not accustomed to long trips afoot, soon becomes tuckered out and along toward sunset, succumbs to fatigue and stops to rest. A few minutes later he is sound asleep by the roadside with faithful Rowdy keeping watch over his master. Here his parents find him. All is forgiven and they hustle him into the automobile, leaving poor Rowdy out in the cold, but Bob refuses to desert his little comrade and a compromise is affected by a promise to Bob to restore Rowdy to his former position as a member of the household.
