The Australian Shepherd took shape on ranches in the American West in the 1800s, likely from Spanish and Basque herding dogs crossed with collie types that arrived alongside sheep shipped from Australia. Medium-sized at roughly 40 to 65 pounds, Aussies have a weather-resistant double coat in merle, black or red, often with white and copper trim and blue or mixed eyes.
Aussies are intelligent, loyal and happiest with a job to do. They bond tightly with family and can be reserved with strangers. Without daily exercise and mental work, that drive may turn into barking, chewing or herding children. The double coat sheds moderately to heavily, so expect regular brushing through Johnson City's four seasons, with heavier shedding as the weather changes. They suit active adopters who enjoy training.
