The Australian Shepherd is a medium-sized herding dog, usually 40 to 65 pounds, with a weather-resistant double coat in merle, black or red, often with white and tan trim. Despite the name, it took shape on ranches in the American West, and that working past explains its stamina and the way it watches everything that moves.
In Jackson, that means a dog that wants a job. Expect moderate to heavy shedding, brushing several times a week, and a need for daily running, training games or puzzle work. Aussies are loyal and often reserved with strangers, and herding instincts can show up as nipping at heels or circling children. Every dog differs, so watch how a particular Aussie handles excitement, noise and new people.
