The Australian Shepherd (affectionately called an ‘Aussie’) does not actually originate in Australia. It is believed that some Basque farmers brought the ancestors of these dogs with them when they emigrated to Australia, then subsequently to the United States during the 1849 California gold rush.
However, the breed as it is known today was developed in the American Southwest over the next few decades. The Australian dog was crossed with several breeds in an effort to produce an animal able to deal with the harsh temperatures and demands of the American West. Breeding during this period was mainly focused on ability—speed, agility, and endurance--rather than appearance, which delayed the Australian Shepherd’s recognition as a breed.
Australian Shepherds became popular pets after they were featured as rodeos performers in the 1950’s, and later in Disney films such as ‘Run Appaloosa Run’. Australian Shepherds were recognized by the American Kennel Club in 1993.
