Seems like your thread may have slipped between some cracks...oops!
I would suggest looking for a breed specific rescue group in your area. I know most reputable rescue groups will not ship their dogs so, you would need to be willing to travel to meet & pick up your dog.
I might also mention that many rescue groups are in desperate need of foster homes, too. Something you might want to think about.
With rescue groups many things are dependent upon finding your dog. Does your apartment have an enclosed patio or yard. Do you work and if so, how many hours will your pet be home alone? Some will not approve a home with a child however, you may qualify for a larger Yorkie.
Well, I just wanted to wish you success in your endeavors to find your second

furbaby to add to your family!
