Despite the name, the Australian Shepherd took shape on ranches in the American West during 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 eyes that can be blue, brown, amber or a mix.
Many Aussies are intelligent, devoted and tireless, happiest with a job to do. They tend to bond closely with family and can be reserved with strangers. Without daily exercise and mental work, herding drive can turn into nipping at heels, chewing or barking, so they suit active adopters who enjoy training and can handle a coat that sheds heavily.
