  I was told by my breeder that she has had no LS in her lines but my dog (who did not show symptoms for 1 1/2 years and who even cornell didn't think he had it based on BLOOD panel and the looks of him) has multiple external ones.  So it can pop up even in health lines.  ...and yes vets says he was born with it.
