OP I don't know where you are exactly in AL but I just did a search on Petfinder for zip code 36688 for yorkies and found this:
1,997 DOGS NEAR 36688
You don't call in most cases....you complete an application. A really good rescue will work with you once you complete the application to show you are a good home. They will find a good fit for you!
I hope that anyone on this thread who is trying to help you get a yorkie, does a vet check on you and home visit prior to placement. That is really how it should be done when buying OR adopting. It always worries me when I see posts online like this. Whether it be people giving pups away or people searching.
