I disagree actually. The lay person watches one dog show a year (or, maybe two), on TV, which is always a bad angle to evaluate conformation, and then makes claims that the dogs have changed dramatically in the last 50 years (or, s
“since I was a kid”) and are crippled and have “crooked backs and bad hips.”
Which is why the then go and pull random photos of other GSDs from years back, which may or may not have been shown in conformation or bred for anything in particular.
If they saw the same dog walking down their street (which, maybe actually even happens) they probably wouldn’t have thought that the breed has changed very much, or made claims about their general health as a breed.
Has the conformation of the GSD changed much in comparison to other breeds? I don’t know. I think you would have to ask someone who has been active in the breed that question. Because I don’t think the lay person, or even someone that is active in another breed can tell based on a few random internet samples.
