Aussies are one of those breeds that crave a lot of interaction, and simply don’t do well when they are left alone for too long. The bottom line is that you should not leave Australian Shepherds alone for 7 hours or more. Most experts recommend not leaving them alone for more than 4 hours; however, this all depends on your dog and his own tolerance.
