That didn't stop her from sticking with her owner, Dorothy Schnabel, when she wandered off and got lost right at the end of June. Schnabel has Alzheimer's, and would walk daily with Duchess. One of those days, she didn't come home. A rescue effort was launched when her husband returned home a couple of hours later and realized his wife was missing.
It turns out Schnabel had fallen into a nearby ravine. When rescuers found her, she was confused but able to talk to them. She was suffering from dehydration. And Duchess had not left her side. Even as Schnabel was being loaded into the ambulance, Duchess didn't want to leave her, trying to jump onto the stretcher and jump into the ambulance.
I think a lot of people hesitate to adopt an older dog, especially from a shelter, because they're worried about whether "the bond will form". Well. I guess it should be taken on a case by case basis, but for Duchess and Dorothy Schnabel, it seems to me that bond is there.
