The Koolie's history is rooted in 19th-century Australia, with ancestry believed to trace back to British herding dogs brought over by European settlers, potentially including the Blue Merle Collie and the Black and Tan Collie. There's also a theory suggesting a connection to the German Tiger, a herding breed. Farmers selectively bred these dogs for their herding skills, stamina, and ability to work in harsh Australian conditions. The focus was always on working ability rather than a strict breed standard, leading to some variation in appearance. The Koolie Club of Australia was formed to preserve the breed's working heritage. While not yet recognized by major international kennel clubs like the AKC, the Koolie is registered with the Australian Sporting Registrar and other working dog registries.
