The Kelpie is alert, eager and untiring at work. Stockmen value its ability to act on its own judgement when it is out of the handler's sight. It is devoted to its owner but tends to become restless without regular work. Casterton in Victoria holds a yearly Kelpie Muster that includes an auction of working dogs.
It is a lithe, athletic dog with a fox-like head, pricked ears and almond-shaped eyes. The short coat has a dense undercoat beneath a harsh, straight outer coat. Show colours are black, black and tan, red, red and tan, fawn, chocolate and smoke blue.
The Australian Kelpie spread rapidly through the pastoral districts in the late nineteenth century. Graziers and drovers valued it for handling large mobs with little direction. In time the breed divided into two lines. The working Kelpie is bred for performance and accepted in almost any colour, while the show Kelpie is bred to a written standard and recognised by kennel clubs. The Kelpie was developed to gather, drive and pen sheep, and it is also used with cattle and goats. In crowded yards it will run across the backs of tightly packed sheep to reach the front, a habit known as backing.
