If you contact a Yorkie Rescue in your area and explain what happened, and ask if they will Post a Curtesy Listing via their Petfinder account for your Ad for rehoming Emma.
You can also ask them if they know of anyone looking for a Yorkie that Emma might do well with.
Understand that I am not suggesting you give her to the rescue, simply saying that I often see "Curtesy Postings" on petfinder and this may help you rehome her faster
