Relevant for any working breed

To anyone who regularly works with both show-line and working-line German Shepherds, it will come as no surprise that a 2019 study (Sarviaho R, Hakosalo O, Tiira K, et al.) analyzing over 173,000 genetic markers across 330 German Shepherd Dogs confirmed that show lines and working lines are in fact genetically distinct populations.

Working lines have been selectively bred for traits like nerve, drive, aggression, and functional performance, whereas show lines shifted their focus to appearance, conformation, and movement for the show ring. Over time, this prioritization of looks over ability has significantly reduced the working capacity and temperament of show-line dogs.

Despite these genetic and functional differences, kennel clubs still register both lines as the same breed. As a consequence, the standards and judging of the breed survey have been progressively watered down to ensure show-line dogs can continue to pass. Similarly, IGP has gradually lowered its standards at least in part to allow show-line dogs to remain competitive.

But this erosion of standards doesn’t just impact show lines. It ultimately harms working lines, too. By continually making it easier for dogs bred without true working temperament to participate, the incentive to maintain real, breed-specific working traits diminishes.

This is not intended to be an attack on show line dogs or breeders. I own a show line GSD and I love her to death. But we must speak honestly about what is happening to our breed as the traits beloved by working dog handlers are set aside in favour of traits that make for better pets or better performance in the show ring. Breeds don’t lose their identity overnight. They lose it through a cycle of lowered expectations.
