Shepherd is a label for a type of dog rather than one breed. On listings it usually means a German Shepherd or a mix, but it can also cover Australian, Belgian, Dutch and English Shepherds and crosses with Labs, Huskies and others. What they share is ancestry in herding and flock-guarding, where dogs gathered, moved and protected livestock.
Most are medium to large, between roughly 45 and 90 pounds, with a thick coat that sheds. Many are loyal, quick to learn and watchful, and some are reserved with strangers. In West Palm Beach, that means a dog who needs training, steady exercise and a cool place to rest, and who may notice every delivery truck and neighbor. Age, mix and temperament vary a lot, so the dog in front of you matters more than the label.
