I agree, I think it is very unfortunate that many breeds
have been ruined by humans not being carefull and created many of the disease problems we see today.
Fortunately many of the breed clubs are working
with Vet. Universities in trying to repair this wrong by
Sending them DNA samples and money for their
research. By working closely with the Vet schools, someday
we might fix the wrong that we created.

As for Show dogs not being working dogs.
I do not agree with this. You can look at some of
pedigrees and not only will they have a CH next to their name but also CD, CDX etc.
So just because they look pretty doesn't mean
they can't work too.
