"Sadly German Shepherd Myelopathy is unique to the breed and breeders that are breeding without this test should be dragged out to the nearest ally and worked over.. Twice."
Ha ha, tell us how you REALLY feel! Perhaps German Shepherd Myelopathy (not DM) is unique to GSD's, but there is NO reliable test FOR GSD's. It's worse to spread a false idea AS IF it were true, than to reject an idea that proves nothing.
