Sheep Dog on an adoption listing is a type, not one breed. It usually points to a herding dog or a mix from the family that includes Border Collies, Old English Sheepdogs, Shetland Sheepdogs, Australian Shepherds and Collies. Adopters can meet anything from a sleek 30-pound dog to a shaggy one near 90 pounds, so look at each dog's size, coat and energy rather than the label alone.
What these dogs tend to share is a quick mind, close attention to their people and an instinct to gather and steer moving things. Many are sensitive and happiest with a job, such as training sessions, dog sports or structured fetch. In Sacramento's mild, dry climate that work can happen outdoors most of the year. Without enough to do, some herd bikes, joggers or children.
