All I can get out of them is that it's inheritance factor is hard to trace...and they don't really know how or why it is passed on........they agree that probably only one parent might have to be the carrier and that it is inherited differently in other Then there are vets that say esophagus is recessive and both parents have to carry it. It has also been said that all the genes have to fall just right to have it. So who knows for sure, how, when and why it shows up out of the blue. Why does someone get just one mega puppy and someone else gets the whole darn litter with it? Joyce MyJoy Shepherds Home of Sel. Exc. Ch.
