Sorry it didn't work out for Mindy...but, could you entertain the thought of surrendering her to a local breed specific rescue?
As a foster mom for YTNR (
Yorkshire Terrier National Rescue Adoptions and Shop), I can assure you that this would be the best chance for her to first be in a foster mom's home dedicated to securing a family & home for this little girl.
They are experienced in screening potential homes and thus reducing the chances of her being adopted & returned when things don't work out.
Here is a list of rescues that could help Mindy:
