The Australian Shepherd took shape on Western ranches in the 1800s, not in Australia, from herding dogs crossed with collie types. Medium-sized at 40 to 65 pounds, an Aussie has 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. That coat handles South Dakota cold well but sheds heavily as the seasons change.
Aussies are intelligent, loyal and happiest with a job to do. Many are reserved with strangers and may herd children or other pets by circling or nipping heels. Daily exercise and training keep that drive productive, so they suit active adopters who enjoy teaching tricks, hiking or agility. Dogs vary, so each dog's personality matters more than the breed label.
