BROOKLYN, N.Y.  -- New York City police have released surveillance video showing a yapping small dog helping to foil a stick-up at a New York City mom-and-pop pharmacy.

The three holdup men fled empty-handed after being confronted by the owner and the frantic dog, WINS-AM reported.

It happened June 9 at the New Trend Pharmacy in Brooklyn.

The NYPD tweeted the footage Thursday.

The video shows one of the robbers, who has a gun, climbing over the counter. He also had on a white mask and surgical gloves.
