Tthe problem is that "from the start", breeders did not know the ins and outs of dwarves and at one time, used them to reduce size as they simply didn't know better. Without any ill intent, the situation was put into play.
That is true Jill, however, when the problem was being recognized in the beginning, they KNEW something was terribly wrong and would hide the "misfits" out "behind the barn" or do away with them at birth and not tell people about it.
What really bothers me, is that even today, people are still often made to feel ashamed of dwarfism in their bloodlines. So where, at what point does it become acceptable to mention the bloodlines of one's dwarf?? After the parents are dead? After the famous grandparents and great grandparents are dead?
I would think that if I bought a stallion that sired a dwarf, that no matter how famous his bloodlines were, or are in the show ring today, being the owner of that foal, I should have everty right to "tell it like it is" without being "shhhhhh'd" back into my corner. OR, if as in this case, I had bought a mare in foal, and a dwarf foal resulted, because I own that foal, I should be able to disclose the parents too, because it is the foal's pedigree which comes with buying a reg'd foal. (in this particular case, it sounds like no stallion service certificate was issued, but I am meaning in most cases where people are buying/selling reg'd horses) Sure, you can say the foal would not be reg'd, but again, not necessarily so...I have seen definite dwarfs that ARE reg'd, so yes, if you can get the angles just right on some of the more minimally affected ones, then I am betting they do get through quite often. And with DNA available, there would be no disputing who the parents are.
I personally feel that even today, some of the most famous, well known farms in the industry are NOT revealing the truth about dwarf foals born on their farms. Some do, and kudos to them. I think it's time for eveyone to come out of hiding!! I can't wait until that test becomes available!! That in itself will be the singlemost BEST thing that could ever happen to this breed!
