Debra, I know the math but I am going to side with the geneticist who has done genetic studies on this issue and shown that after 5 generations the genetic contribution is not significant.
Again, traits are not the same as genes. You breed blonde hair and blue eyes to brown hair and brown eyes, then breed every generation to brown/brown, you eventually have no blue eyes and limited blonde. But the genes are still there in some. But again, we totally agree one breeding and right back to the old lines won't help.
I also keep getting the perception that the health of the breed is doomed and the only way we can save it is through importing native stock.
Given the only information I have access to, which is the OFA database, if you look at dogs born in the last 10 years the number of actual publicly available health records is low for a number of the tests.
If you look at the overall breed statistics…
The easiest way to promote the health of the breed is for more breeders to test and share information (good or bad) about the health of their dogs so that more informed breeding decisions can be made in the future.
I don't know either. And your post was a duh moment for me since I didn't think to look before. Thanks. But here is the problem… neither does BCOA or even the breeders. When you have so few testing, you don't know. That's a bottom line.
Not sure where you got your numbers but I used OFA:
Lets look at it this way… In all this time, while the 3,720 is good for fanconi, and while the hips show a lot more than say 5 yrs ago... the rest is appalling. It indicates the same issue with Chows, people submitting basically only where they know the dog is clear for the most part.
We really need to do what some European countries do... you submit, it is open to the public. Some breed clubs will not list your litters unless the CHIC tests have been done. I'm just saying that looking at those numbers concerns me. The percentages are utterly meaningless with such a small number tested.
I am not advocating a Breed Warden system where you have to do all the tests and get permission to breed in order to register your litter, but I do think BCOA would do great to list dog litters FOR FREE from all breeders where the sire/dam had all their tests done.

The other problem though are things you can't test for… such as increase in autoimmune issues, types of cancer or other problems. So unfortunately if right now you simply went with those dogs with 2 or 3 (which is a sad number... in Rotties we look at 5 to 6 generations of clear testing) generations of the recommended tests (obviously current generation Fanconi is all) you would limit the gene pool so severely we'd be in worse shape. Am I seeing this wrong?
