Overview:

John Livingston is a rich mama's-boy, who owns a blooded dog named Paul. Paul meets Maggie Mutt, and Paul, being a pedigree canine and somewhat of a cad, lures trusting Maggie to the barn to have his way. He then departs for his palatial doghouse at the Livingston estate. Meanwhile Maggie is broken-hearted and also finds that she is in a "family way", and gives birth to a pup she names Hank. Maggie tells Hank to find his "human ", and departs the scene. Hank goes to the park, meets a "human" named Mary Kelly, who is a homeless waif and sweetheart of poverty, and the two adopt each other. Later on in the park Paul comes strolling along with his 'human', John. A child falls into the lake and Paul and Hank team up to save her.
