The Australian Kelpie is a lean, prick-eared herding dog developed in the 1870s from Scottish working collies to move sheep across hot Australian stations. Most stand 17 to 20 inches tall and weigh 25 to 45 pounds, with a short, weather-resistant double coat in black, blue, red or tan, with or without tan points.
Many Kelpies are alert, quick to learn and devoted to their people, though often reserved with strangers. That drive needs an outlet: without a job, a Kelpie may herd children, chase bikes, bark or dig. In Oceanside, where the river trail is shared with cyclists and skaters, impulse control and good leash manners matter. Working-line Kelpies usually have more drive than show-line dogs, and every Kelpie varies.
