Are they Aussies mixed with Border Collies?

Not sure if your post is a joke or not :) If not, then who knows, cross breeds are just that, cross breeds, they only get given names by people who are wishing to sell them to the gullable public for a good deal more money than they are worth. To the rest they are the result of a miss-mate or have been specialy bred usually for a sporting reason (or as a money making effort) and are then sold as a cross breed or a named cross breed such as cockerXspringer or gsdxbc

I'm treating this as a genuine question - although I canot for the life of me understand the title!!

The Australian shepherd developed completely within the United States. In the late 1800's and early 1900's the forerunners of today's Aussies appeared in Californi and n-western states as stock-dogs for the Basque shepherds that accompanied the vast numbers of sheep then being imported from Australia. These "little blue dogs" impressed the American ranchers and farmers, who began using them as well. Breeding was done for working ability rather than appearance, and occasionally dogs of other herding breeds were bred into the lines. However, today's Aussie still resembles the dogs that came from Europe via Australia, and great numbers of Aussies are still working stock on ranches in the western states.
