Kate speculated how the little pups got separated. It was clear that Sadie was the more mature and brave one of the bunch, and the young shelter employee did not see a mother dog anywhere. So Sadie was probably forced to provide food for her brothers and sisters, who remained in hiding. And when she was out hunting for food, a local dog snatcher probably found her and brought her in.
