"Love me, love my dog," does not appeal to Billy Hallock. He is very jealous of his wife's attentions to her dog "Jean." Florence Hart and Dick Green, a couple of young friends who are engaged to be married, call on Billy and Sue Hallock, and during this visit, they call Billy's attention in a casual way to his wife's fondness for "Jean." Shortly after this incident, Billy and Sue, having engaged seats for the theater, are about to take their departure, when the maid is unexpectedly called away and Mrs. Hallock refuses to go out and leave her dog alone. This convinces Billy that she cares more for her dog than she does for him, and he informs her that it is time for them to separate. He leaves her. Some months later, "Jean," who notices the lonesomeness of his mistress and the different atmosphere of the home, grows very restless and seems to grasp the cause of it all. During the separation of Billy and Sue, "Jean" has occasionally met Mr. Hallock, and she formulates a plan to reconcile her mistress and former master. Mrs. Hallock is sewing on some tiny garments in preparation for the reception of a little stranger when ''Jean," unnoticed, steals one of the tiny garments and runs off to where she knows she will find her master, and insists upon presenting it to him. Billy suddenly realizes what it all means. He hastily follows "Jean" to the home of his wife, where he lovingly and tenderly enfolds her in his arms and asks for forgiveness for his uncalled-for and foolish jealousy of the thoughtful and faithful "Jean."
