The Australian Kelpie is a lean, prick-eared herding dog developed in Australia in the 1870s from Scottish working collies to move sheep across hot, open country. Most weigh 25 to 45 pounds and have a short, weather-resistant double coat that sheds moderately. Colors run through black, blue, red and tan. Show and working lines exist, and working-line dogs usually carry more drive.
Kelpies are alert, quick to learn and loyal, and many are reserved with strangers. Without a job they may nip at heels, chase bikes or bark, so training and structured play matter as much as running. In Lawrenceville, that means planning daily exercise on leashed trail walks or in a fenced yard, and remembering that each Kelpie differs in energy and temperament.
