I rescues Hallie when she was 2.5 and no, she didn't know how to play or socialize. She was very shy and skiddish of everything and everyone. It has been a year and a half and she LOVES to play now, almost like a puppy discovering new toys everyday. I think you have done a tremendous job with Daisy and we can all tell how much she is loved. She will learn to play in her own time and then there will be no stopping her
