Yup.

Either I'm misunderstanding what's being asserted or I think
you've made a think-o. I know you know that the incidence
of hip dysplasia isn't equally distributed among breeds.

I reread that part before I posted it, wasn't positive, so gave
wolfpuppy the benefit of the doubt.

To be honest, what was going through my mind at the time was
that some severe HD-prone breeds have improved statistically and
others have not. So, maybe it was really a think-o. No matter,
mea culpa.

On that note, and to turn this thread to something in which I'm
interested in learning regarding HD, I had a disgreement with a
soon-to-be-vet friend regarding HD improvement of specific
breeds. He asserts that OFA stats are easily manipulated by
breeders only submitting good results. I contend that, to a
certain degree, some (usually less popular) breeds are self-
policing.

Siberian Huskies are one. They have a particularly high
incidence of testing, especially since I suspect they're no
where near as popular a pet dog as Labs, GRs, and GSDs.

Sibes own (according to offa.org), the fifth postion in HD, with
an high number of reports. I'm not sure how to interpret the
trend numbers.

So. Can breeders and owners affect the OFA's percentages? I
tend to believe the best and say no - they couldn't and probably
wouldn't.
