Which specific German organization kept the Weimaraner breed secret and strictly controlled within Germany for many years?

Answer

The Weimar hunting club

For a significant period of its development, the Weimaraner lineage was maintained in relative secrecy and was strictly controlled by the Weimar hunting club within Germany. This exclusivity was intended to preserve the purity and high quality of the working hunting line. This historical control limited the breed’s exposure outside of aristocratic circles until after World War I, when exports, particularly to the United States, began to spread its reputation internationally. This period of isolation ensured the dog was bred almost exclusively for working capability.
