Shepherd is a label for a type of dog rather than a single breed. On Augusta listings it most often means a German Shepherd or a mix, though it can also describe Australian, Belgian, Dutch and English Shepherds and crosses with Labs, Huskies and many other dogs. What links them is ancestry in herding and flock-guarding work.
Most are medium to large, athletic and smart, with a thick coat that sheds. Many are loyal and quick to learn, and some are reserved or protective with strangers. They generally need daily exercise, training and a job to focus on. In Augusta that means a sturdy fence and cooler-hour outings. Ancestry varies, so a dog's own behavior tells you more than the label.
