Thank You for the advise. I so have another dog, babe, a retriever/chow mix and they used to play all the time, Since I work for the Humane Society, we had a dog there that was getting to the point of being unadoptable at only 15 mo., so I brought him home. Hailey and Harley played all the time. I found Harley a home and it was at this point that my golden/chow quite playing with Hailey all the time. That was when I think she started shadow chasing. My husband and I take the girls for a long walk every morning. And my husband finally remembered to bring a frisbee along to see if Hailey would play with it at the school. She loves it so I am trying to see if he can't play frisbee with her more often. But the minuet she starts walking again she chases shadows. Thanks for the good advise. I haven't given up on her and we will be trying other things to keep her mind occupied.
