Despite the name, the Australian Shepherd took shape on ranches in the American West in the 1800s, from Spanish and Basque herding dogs mixed with collie types that arrived with sheep shipped from Australia. 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 or mixed eyes.
Many Aussies are intelligent, devoted and happiest with a job to do. They bond tightly with family and can be reserved with strangers. Expect heavy shedding in spring and fall and regular brushing year-round. The thick coat suits Arlington Heights winters, but the work drive needs outlets like training, puzzle toys and scent games. Dogs vary, so judge each Aussie on its own energy and habits.
