AUSTRALIAN SHEPHERD HISTORY
by Linda Rorem (the original of this article appeared in Dog World magazine)
Little can be known for certain about the origin of many breeds. With regard to the Australian Shepherd, various theories have arisen: that it is of Australian origin; that it is really a Basque breed; that it is of old Spanish origin. The investigating I have done indicates that none of the above theories provides the whole story, but together they may play a part.
Histories of California relate that although there had been many flocks of sheep at the Spanish missions, the number of sheep in the Far West had greatly declined by the time of the Gold Rush at the end of the 1840's. The Gold Rush and the Civil War brought about a great demand for mutton and wool. To meet this demand, large flocks were driven to the Far West from the Midwest and from New Mexico. Sheep were brought around the Horn from the Eastern states, and imported from Australia (1). Dogs accompanying these flocks, along with later arrivals, would figure in the background of the Australian Shepherd.
This also explains the making of the English shepherd a little bit!
