Hi Tammy, First let me say that I am so very thankful that the subject of DM has been the topic of discussion often, in resent months. As far as your situation, I would wonder if the owner of the Dam had the "Flash" test (as I understand it is no longer used) instead of the DNA test. The reason I question that is because, as you know, the DNA test for DM, whether it is done through OFA or DDC, is a simple cheek swab which certainly does not require a vet to perform it. Also there could have been a cross contamination on the swab with the DNA of another dog.

It is situations like this that makes doing these tests important because it helps with trying to determine the validity of the tests. I know that they did not use OFA for their test that is why not on the OFA database she was tested at the vets office and they sent it out for her and called with results when they came back in. I am definitely getting beyond frustrated for none of this is panning out.
