Top Dog is a 1995 buddy cop action comedy film directed by Aaron Norris and starring Chuck Norris. Written by Aaron Norris and Tim Grayem, it was Norris' last film to release theatrically before he shifted to direct-to-video films for several years.
In the film, Norris' character, Jake Wilder, is partnered with Reno, a police dog, whose handler was killed. Jake and Reno investigate a plot by domestic terrorists to attack a conference on unity. Jake and Reno survive assassination attempts and several hand-to-hand fights with the terrorists and eventually discover enough clues to foil the attack. The film is set in San Diego and was largely filmed there.
The film received mainly negative reviews, and its box office was negatively impacted by the timing of its release, only 9 days after the Oklahoma City bombing.
