*The breeders in our group stated that they are more prone to the issues there trying to put all on merles...I own both including solid white and never as of yet had an issue with sight or hearing on any of them...But I do know the genetic testing proved inconclusive on the merles and one reason the lab stopped doing the testing... * On Sat, Nov 6, 2010 at 10:33 AM, OKreationZ <[email protected]> wrote:
