However, we can estimate:
* The German Shepherd is one of the most popular dog breeds globally. This suggests a large population.
* The American Kennel Club (AKC) ranks the German Shepherd as the second most popular breed in the United States. This gives us a sense of their popularity in one country.
Based on these factors, we can say that the number of German Shepherds in the world is likely very high, but a precise figure is unavailable.
