I bought my Abby when she was 16 weeks old, I have had her for 9 weeks and she still acts like she's afraid of everyone, even me at times. I don't know if she was abused, or just never taken up any time with. I hold her alot and she sleeps with me at night, but she still acts afraid. She won't come to me when I call her. I have to go and pick her up and she runs from me. This is my first yorkie, do they all act this way?
