The Australian Shepherd, despite its name, originated in the United States, not Australia. This breed's development began with the arrival of the Conquistadors in the 1500s, who brought sheep and herding dogs to the New World. The breed was further shaped by Basque settlers and German shepherds who interbred their dogs with local ones. Known for its herding skills, the Aussie became a favorite among ranchers and cowboys, especially in Western states like Colorado, California, and Wyoming. This breed's name is a misnomer that confuses many regarding its true American roots.
