Which breed was intentionally crossed with original Vizsla stock to achieve the heavier coat of the Wirehaired Vizsla in the 1930s?

Answer

German Wirehaired Pointer

The development of the Wirehaired Vizsla was a deliberate act of artificial selection occurring around the 1930s, aiming to enhance hardiness for colder European working conditions. Breeders achieved this by introducing genetic material from other breeds known for robust coats. The specific infusion used to impart the defining wiry texture, pronounced eyebrows, and beard was the German Wirehaired Pointer, thereby creating a distinct variety within the existing Vizsla lineage while maintaining the shared *Canis lupus familiaris* classification.
