More: Cookie is a tri-colored Sheltie. Her coloring is black, tan and white. She is a very sweet girl, but she really hates "metal dogs" (cars), and gets very upset when they race past her on our walks. Cookie is a rescue dog who had two previous owners who did not understand the timid and fragile nature of Shelties. Cookie was very anxious when we first adopted her, but she has grown into a happy and confident companion.
