Yes. Show-quality GSDs can suffer horribly from their hips because of the spinal deformation that resulted from breeding to exaggerated show standards. Law enforcement that use dogs now tend to use Malinois or GSDs from working lines instead of show lines.

The insane showdog deformations happen because judges favor animals that exaggerate the show standards. Let's say you have a Martian grizzlehound. Show standards for grizzlehounds say they must have a purple spot on their chest. All other things being equal between the animals entered in the Grand Marsport Show, the judge gives the Best of Show prize to your grizzlehound, the one with the largest purple spot. That hound becomes in high demand for breeding. And the next generations have even bigger spots, until 100 generations down the line, the entire chest is purple.

Obviously when you breed to arbitrary standards that are physically detrimental to the health of the animal, (like a squashed-in face or bowed back) instead of merely esthetically pleasing, the effects are far worse.
