El propósito de la Unidad K-9 del Distrito 7 es el de ayudar a los oficiales en las áreas de rastreo de sospechosos, vehículos y de búsquedas en edificaciones. Precinct 7 is fortunate to have the dynamic duo of Deputy Nguyen and Argo.
Deputy Nguyen is a certified handler. His faithful companion is 2 year-old Argo. Argo is a German Shepherd and has been trained as a dual-purpose dog, meaning he can perform in many different areas of police work from narcotics to patrol.
