The Australian Kelpie is a lean, prick-eared herding dog developed in Australia in the 1870s to move sheep across hot, open country. That heritage shows in its stamina, toughness and sharp focus. Today there are show Kelpies and Working Kelpies, and the working types often carry more drive. Adults usually weigh 25 to 45 pounds and stand 17 to 20 inches tall.
Most Kelpies are loyal, alert and quick to learn, but a Kelpie without a job can herd children, chase bikes, bark or dig. They tend to do best with people who enjoy running, training and dog sports. The short double coat sheds moderately, and Kelpies vary a lot, so don't assume any one dog will match the breed description exactly.
