When I moved west to San Francisco 20 years ago, I met my soon-to-be husband’s dog, Heidi. She was the first full GSD I’d ever gotten to know and I fell in love. We used to play Frisbee with her in Lafayette Park, across the street from our apartment. Heidi was very obedient with me but COMPLETELY dialed in to my husband. I was playing with her in the park one day and, just to see what would happen, my husband leaned out of our 6th-floor apartment window, hundreds of yards away on the other side of the street and yelled, “Heidi, sit!” It was barely audible and she couldn’t see him but Heidi planted immediately. It was amazing.
