HAS has NOTHING to do with type of GSD. the ASLs are just as at risk. Most of the dogs I know that pass from Hemangio are over 10....closer to 12 - and seriously, it is a much quicker way to go than slow descent into DM.....I think you will have an easier time getting a sound West German Show line if that is the look and personality you want.
