If she talked ED: A Maybe they mistaken with HD, very different things.
ED is classified by numbers, so ED: 0-0 only.
But I hope people will not use this as excuse for not do the ED results or breed with ill dogs.
By the way, I agree with the club about first know the actual breed situation before make a rigorous selection.
If it is really spreaded, so they will need to plan about the usage of affected dogs with still acceptable results ( ED 1-1), like is done with Rottweilers or Labradors, well, if it happen at this point I think it will be a pretty sad scenario.
