At the moment it's still playful, but already in a few months the dog quartet will take care of law and order.

"Woof! When we are big, we hunt criminals!"

The Rottweilers originate from a litter of nine puppies - it is already the third generation in the police service. Grandfather Festus and Papa Quintus were already service dogs of the Duisburg police.
