What was the specific German Wirehaired Pointer sire crossed with Vizsla bitches to start the breed?

Answer

Astor von Potat

The initial crosses foundational to the Wirehaired Vizsla involved pairing working Vizsla bitches, such as Zsuzsi and Csibi, with a German Wirehaired Pointer sire that was carefully selected for its completely liver coloration. This specific sire used in the foundational pairing was named Astor von Potat. The intentional use of a sire with this coloration, combined with the desired coat genetics present in the Vizsla line (suggested by Zsuzsi’s pedigree), was critical to achieving the desired outcome for the new breed standard.
