Hmmm I'm not really sure other than exercise. Perhaps try to get her really focused on you first by giving really basic obedience commands and then rewarding with a tasty treat? I'm not sure how Heidi is but both Tommy and Tasha are very treat-driven and if they realize they can earn treats easily, they get VERY focused on me. If you can get her really zeroed in on you it might prevent her getting the zoomies
