Shepherd is a label for a type of dog, not a single breed. On adoption listings it most often means a German Shepherd or a German Shepherd mix, but it can also cover Australian, Belgian, Dutch and English Shepherds and crosses with Labs, Huskies and many other dogs. What they share is ancestry in herding and flock-guarding work.
Most are medium to large, athletic and smart, with a thick shedding coat and a strong wish to stay near their people. Many are loyal and quick to learn, and some are reserved with strangers. Because ancestry varies, a Shepherd's size, energy and coat can differ a lot from dog to dog. In Naples, that thick coat is the main thing to plan around, since the heat rarely lets up.
