I am SO sorry to hear about your lost little lady...I can't even imagine!! As someone already said...put up posters...maybe saying that a woman in a dark car at (whatever store) was seen picking her up....maybe if you say that she is sick and needs meds this would help...Unfortunately yorkies are the #1 dog for theft
....That being said..if someone took her they probably aren't going to return her...(I HATE to say that! ) Being chipped doesn't always mean you will get them back either....it would take an honest person to bring them to a vet and tell them they found the dog and ask to scan them.. Maybe go to the store where she was seen being taken and ask people if they saw anything..I hope a pray they return your little girl...
