According to the American Kennel Club Australian "Aussie" Shepherds are
"...the picture of rugged and agile movers of stock. Aussies exhibit an
irresistible impulse to herd, anything: birds, dogs, kids. This strong
work drive can make Aussies too much dog for a sedentary pet owner.
Aussies are remarkably intelligent, quite capable of hoodwinking an
unsuspecting novice owner.
