Fidelity (1911)

A mother and child live alone except for a big St. Bernard dog. One day the little girl dies and both mother and the little girl's playfellow, Don, seem grief-stricken. Later, in order to pay the rent, Don is sold, but is not happy in his new home, and day by day carries flowers in his mouth to the grave of his former little mistress, where he is finally found by his former owner's mother and they are never parted again.
