Wow! This is crazy!!!
Everything I am thinking has already been said but I am so sorry you have been hurt like this. Pettiness is very ugly. Whatever this person's agenda was, it has obviously backfired. Your breeder didn't believe her and you've got an entire board of yorkie lovers backing you. We all know the truth- you are an AWESOME yorkie mommy!
