Breed History:

The Koolie is an Australian working dog developed in Australia during the 19th century for herding livestock across vast and challenging terrain. The breed was developed by crossing imported British herding dogs, particularly Collie-type dogs, with other working farm dogs suited to Australian conditions.

Despite the name, the Koolie is not directly related to the modern Collie breeds. It was bred almost entirely for intelligence, stamina, agility, and working ability rather than appearance.

Koolies became highly valued by Australian farmers for their versatility in handling sheep, cattle, goats, and even poultry. Today, the breed remains respected as an exceptional working dog and active companion.
