That's great!
My brother found a small chihuahua running around our neighborhood park and brought her home. We put up signs and the owners showed up - a high school boy. He had found her on CL and bought her for his GF but she had to stay at his house (her folks wouldn't allow her to be there). Well, BF's mother opened the door and pushed her out a few times because she didn't want her. My mom told him that if anything happened, that she would give him $50 for her. Two days later, she was back at my folks'. That was 3 years ago and little Daisy is one spoiled lady...
I hope that she finds a nice home!! I'm so glad you picked her up! Poor thing is probably terrified...
