Duisburg. Rottweiler puppy Amigo wants to become a service dog when he grows up. Henrik Richter, his owner, trains with him every day.

At the presentation of the poizei on the "Blaulichtmeile" in Düsseldorf on the last weekend of August 2016 on the occasion of the 70th birthday of NRW, the Duisburg police were also represented with a shepherd dog and "our" service-rotti Quintus from Avalon with service-dog handler, police chief commissioner Henrik Richter.
