Although mercifully brief and nowhere near as doggedly eager to please as Turner and Hooch or K-9, this competent quota quickie from Derek Twist is, in all honesty, "mutt ado about nothing". In one of his few movie excursions, Tim Turner plays a bobby who adopts an alsatian stray and has reason to break out the Bonio when it helps him on the trail of his friend's murderer. It's hardly a baffling mystery even Scooby Doo would have sussed it! However, it's always nice to see class acts like John Le Mesurier and Christopher Lee, no matter how briefly.

When his colleague is killed during a chase in Kentish Town, London bobby Frank volunteers to become a dog-handler.
