I'm so sorry you are having to go through this...
Have you contacted your local media? (sorry if you did already and I missed it in the postings). Most of the time they won't do a story about one dog missing (it could have run away), but if one of the vets is talking about a 'yorkie theft ring' (and they can show pictures on his wall of the missing yorkies), this could be your way in... The more people are affected, the better your chances are of getting a story in the paper or on tv.
