@pedro:
hi, i talked to another breeder and she has never heard if a test coming back at risk!, and told me the same thing as ivoss was saying before that that is not a sure resault!. that it's not a diagnoses!to see if i can get another test at no charge!!!.
Lisa checked with Jon Curby who works with the U of MO lab and OFA and it does mean Prob. Affected. They just changed the name to At Risk, however we believe that they will be changing it back. Jon was going to check and see why it was changed, but again, it still means the same.
Most important thing now is to keep your Basenji as healthy as possible and I also agree that neutering him would be the responsible thing to do.
