"In this sequel to the action comedy K-9, police detective Dooly (James Belushi) has been teamed up with Jerry Lee (Mac), a German Shepherd police dog, for nearly ten years, but Jerry Lee isn't as young as he once was, and Dooly's superiors suggests that maybe it's time that the dog was retired from the force. Dooly isn't pleased with this idea, since Jerry Lee has become one of his best friends over the years, but when the dog can't keep up with chasing a gunman during a shootout, Dooly is overruled and he now has two additional partners -- Zeus (Lucan), a young, strong Doberman Pincher, and his new trainer. K-911 also stars Christine Tucci, James Handy, and Wade Williams."
