The Koolie (or Australian Koolie) is one of Australia's oldest working dog breeds, used by stockmen since the early colonial era to muster cattle and sheep. Developed from British working collies brought by settlers, the Koolie has long been bred strictly for ability rather than appearance, resulting in a highly varied but supremely capable herding dog.
Intelligent, agile, and tireless, the Koolie often sports an eye-catching merle coat and sometimes striking blue eyes. It works both "heading" and "heeling" as needed and bonds closely with its handler. Like other elite herders, it has enormous energy and a sharp mind, making it a fantastic partner for active owners and dog sports but a poor fit for sedentary households.
Koolies are intelligent, energetic, and devoted herding dogs, eager to work and quick to learn. They bond closely with their handler and need substantial daily exercise and mental stimulation to thrive.
