Historically, there has been much debate about the origins of the Australian Shepherd. However it is now well accepted that the Aussie is more of an American than an Australian as the name suggests. It appears likely that many breeds played a part in the make-up of the Australian Shepherd, among them Border Collies imported from Australia around the turn of the last century. Today The Aussie continues to work on American ranches as well as being trained to work with physically challenged people, in search and rescue work and as sniffer dogs.
