The Australian Shepherd is an American breed, developed on Western ranches in the 1800s from Spanish and Basque herding dogs and collie types. Ranchers wanted a dog with stamina and quick thinking for moving sheep and cattle, and rodeo shows later made Aussies famous. They're medium-sized, usually 40 to 65 pounds, with a weather-resistant double coat in merle, black or red, and eyes that can be blue, brown or a mix.
In a city like Jersey City, the coat and the mind both need attention. Expect moderate to heavy shedding and regular brushing, plus daily mental work. Many Aussies are loyal with family and reserved with strangers, and some try to herd children, other pets or passing joggers. Dogs vary, so an adult's own habits tell you more than breed averages.
