Despite the name, the Australian Shepherd was developed on ranches in the American West, where its stamina and quick thinking made it a valued herder of 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 eyes that can be blue, brown or a mix.
Many Aussies are intelligent, devoted and tireless. They tend to bond closely with family and stay reserved with strangers. In a city of sidewalks, stairwells and traffic, that watchfulness can show up as barking at noises and herding instincts toward kids, bikes and other dogs. They shed moderately to heavily, so brushing is a regular chore. Aussies do best with active adopters who enjoy training, though each dog's energy and personality vary.
