Shadow Chasing!

Help! I have a 7 month old goldendoodle and she is awesome...but for the last 2 months she has been chasing hers and ours shadows! She doesn’t hurt herself or other things, but I am worried this behavior will turn into the OCD problem. I can redirect her with toys, games and food but she will go back looking for a shadow minutes later. We did use a laser light for a few days as a training tool(NOT GOOD) this made the chasing worse. That’s why we stopped. And for an added bonus, she stalks our metal refrig waiting for the next shadow victim! She scratched up the poor frig wicked bad... Any advice, anything would be great! HELP MY TESSA and my frig! Jenn
