Despite the name, the Australian Shepherd was developed on ranches in the American West in the 1800s, from Spanish and Basque-type herding dogs and collie types that arrived with sheep shipped from Australia. It's a medium-sized dog, usually 40 to 65 pounds, with a weather-resistant double coat in blue merle, red merle, black or red, often with white and copper trim and eyes that can be brown, blue or both.
Aussies are bright, loyal and happiest with work to do. Many are reserved with strangers and may herd children, bikes or other pets by circling or nipping at heels. In Norwalk, busy sidewalks and crowded shoreline paths make good leash manners and early socialization worth the effort. That thick coat also sheds heavily, especially in spring and fall, so regular brushing is part of the routine.
