Where is there a higher concentration of GSD working lines found?

Near specialized training academies or government facilities

While German Shepherds are numerous as companion animals across many Western European and American households, the density of dogs specifically identified as 'working lines' often varies geographically based on institutional need. A higher concentration of these dogs, bred for specific protective lineages and advanced performance, is typically found situated near centers of professional deployment. These include specialized training academies, major metropolitan police K-9 units, and international border patrol facilities where high-demand service work requires dogs with proven lineage and rigorous training preparation.
