How did military service during the World Wars affect the breed's international acceptance?

Served as an unintentional, large-scale recruitment drive internationally

The extensive utility demonstrated by German Shepherds during the World Wars played a crucial, albeit unintentional, role in promoting the breed globally. Their effective deployment in various capacities, likely including military service roles, showcased their inherent capabilities—intelligence, loyalty, and strength—to a wider international audience. This high-profile, large-scale application outside of traditional herding roles served effectively as an international recruitment drive, validating their utility in new, demanding environments and accelerating their geographical dispersal beyond Germany.
