As an example, I contend that the incidence of Siberian Husky
HD, going by the breed's OFA records, has been reduced by
conscientious breeding over a number of generations. My friend
contends that the OFA numbers and trend data are skewed by
selective reporting of individual results from within the
litters.

I know people who test and people who don't test. The
situation is almost certainly different from many/most other
breeds since the people I know who don't claim that they
don't need to because they're sleddogs and if there are hip
problems they'll come out while working. It is the case
that people who run their dogs do tend to have relatively
good eyes for lameness and other physical problems.

The people I know who do test tend only to test dogs that
are considered breeding candidates, although I do know
people who test all their dogs. I guess whether or not this
matters depends on the questions you're trying to answer.

[I'm watching the Iditarod ceremonial start, and Karen
Ramstead just started with two Can.Ch. dogs as her leaders.
She's apparently been passing out fistfuls of Canadian flags
to spectators. The cut-outs in the doors of her dog truck
are the shape of maple leafs. She's going for a purebreed
record for the race, so here's wishing her the best.]
