Go there first and if she's been adopted out ask them what date it happened on. Have a picture of her and put it up on the different sights for missing pets and Craigslist letting people know what happened. Someone may take mercy and return her to you. Good luck finding you little girl.
Go to the shelter and see if your dog is still there. I doubt it. But, they will have other dogs.
I would call them n let them know what is going on
