This independent comedy-drama follows a stray dog as he wanders from one New York neighborhood to another, proving a link between the stories of a number of otherwise unrelated characters. The dog's chance acquaintances include a businessman who has skipped out of work and is trying to pick up a free-thinking woman he meets on the street; a guy with a bowling ball who thinks that it might be fun to toss it out of his apartment window; a man trying to make a delivery who is pursued by a pair of toughs; an artist deciding where the first brushstroke should go on his latest canvas; and a man who takes his much younger girlfriend to a bar as he works up the nerve to break up with her. One Dog Day marked the feature debut for writer and director John Hyams; the rock band Kilgore Trout contributed the film's original score.
