Shepherd is a type label rather than a single breed. On listings in Hattiesburg it usually points to a German Shepherd or a German Shepherd mix, though Australian Shepherds, Belgian and Dutch Shepherds, and crosses turn up too. They share roots in herding and guarding flocks, which is why many are alert, trainable and closely tied to their people.
Day to day, that means a dog that wants routine: a long walk, some training and time near the family. The coat is a thick double layer that sheds, and Hattiesburg's rain keeps it damp and muddy much of the year. Because ancestry varies, size, energy and temperament vary too, so let the dog's actual behavior guide you more than the label.
