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.

"Wolfpuppy": check the OFA stats. Also, read "Control of
Canine Genetic Disease" by George Padgett.

My research shows that it is fairly equally distributed, and why wouldn't
it be? Are you implying that breeders of one particular breed are more
apt to be dishonest than another? That makes no sense.
We're implying you need to do more research because you don't know what
you're talking about. HD is not evenly distributed between breeds. Some
breeds have markedly more HD within the breed than other. Inbreeding does
not cause HD.

HD is not caused by a virus. It is not caused by a bacterium. It is not
caused by injury. It is not caused by poor diet. It is not caused by age.
It is caused by genetics--abnormal genetics, obviously, not normal genetics.
Abnormal genetics is caused by inbreeding, and as for looking it up, I have
already done that. I have no agenda here; I didn't just 'make this up'.
Maybe some breeds have higher incidents of HD than others, but that may be
due to numbers bred vs other breeds. I don't know that, nor do I care. I'm
done. Believe what you wish.

No. It's not. For one thing, it's spelled dysplasia. Doing a search on
that or even a cursory look at the OFA website (www.offa.org) would give
you reams of information about the causes of hip dysplasia. Inbreeding is
NOT a cause of dysplasia.

Now hip dysplasia is genetic. That is true. And it's also a multi-genetic
inherited disease in which the mode of inheritence is not clearly
understood. But it is found in inbred dogs, outcrossed dogs, mixed breed
dogs, purebred dogs, wolves, and even cats. And there are many "inbred"
lines with absolutely no hip dysplasia.

All inbreeding does is make an organism more homozygous. By inbreeding
properly, you can actually eliminate certain genetic diseases from lines,
which is why the Portuguese Water Dog has made huge strides in eliminating
HD even though it has a very small gene pool.


If you want to get into more detail than that, you will have to ask a
geneticist. If you are trying to pin me down by making me say that all
inbred pups will develop this condition, there is no way I could do that.
But if you want to avoid this condition, then I would say that by not
breeding dogs too closely related would be the way to go. To be
absolutely sure, you would want to have the parents hips x-rayed, since
x-rays in too young a dog wouldn't show anything.

You know, you really ought to think a bit before you spout off about stuff
you clearly have no understanding of. Avoiding "inbred" dogs will not keep
you from getting a dog with HD. HD occurs in all dogs, feral, mix, pure,
outcross, inbred. All dog breeds are inbred, that's what makes them a
breed. Yet clearly there is a difference between the incidence of hip
dysplasia in Bulldogs (ranked #1 with 73.6% dysplastic) and in Italian
Greyhounds (ranked #146 with NO HD found and 68.3% Excellent). Oh and
German Shepherds? 39 with 19% dysplastic.

You people are so ****in' anal about the spelling. Alright, I mispelled it.
I stand by my post, though.

Please. It's dysplasia. You might have more credibility if you got
the name of the condition correct. And again, breeding dogs that are
closely related doesn't magically produce hip dysplasia.

Again, this points out the reason one should go to a reputable breeder.

Reputable has nothing to do with it. Responsible does.

Come on, Sally, quit trying to win an argument with semantics. Reputable,
responsible...same thing. As far as misspelling dysplasia, that was the
fault of my spell checker, and if you check one of my earlier posts, you
will see that it was fully punished for that error.

No. Look them up in a dictionary. In this context, reputable means
having a good reputation; responsible means doing the right thing.
They're not synonymous.

(type dysplasia and hit spell checker--see what you get...hmmmm??)

I don't need a spell-checker, thanks.
