The Australian Shepherd took shape on American ranches in the 1800s, where Spanish and Basque herding dogs crossed with collie types to work sheep and cattle. Aussies are medium-sized, usually 40 to 65 pounds, with a weather-resistant double coat in merle, black or red, often with white and copper trim and blue, amber or mixed eyes.
The coat sheds moderately to heavily, so weekly brushing, and more during seasonal blowouts, keeps it manageable through Roanoke's four seasons. Aussies are bright and loyal, often reserved with strangers, and they want a task. Daily exercise, training and puzzle work matter more than yard size. Dogs vary, so judge each Aussie by how that dog behaves, not by the breed alone.
