Additional information (Wiki): The Australian Shepherd is a breed of herding dog that was developed on ranches in the Western United States. Despite its name, the breed, commonly known as an Aussie, did not originate in Australia. They acquired their name because of association with Basque sheepherders who came to the United States from Australia.

The breed's general appearance varies greatly depending on the particular line's emphasis. As with many working breeds that are also shown in the ring, there are differences of opinion among breeders over what makes an ideal Australian Shepherd. In addition the breed can be split into two distinct lines - working and show dogs. Working dogs tend to have shorter coats, thinner and are sometimes smaller while the show lines are bred according to breed standard and can have long fur.

The breed is an energetic dog that requires exercise and enjoys working, whether it is learning and practicing tricks, competing in dog agility, or any other physically and mentally involving activity.

Dogs with strong working instinct may show more reserved, guarding behaviors along with a tendency to chase or nip at strangers. Its protective instinct and behaviors can be frightening to children, strangers, and small animals. They are kind, loving, and devoted to those they know. They are very loyal to their owners, and are rewarding dogs if treated well. Because the breed was developed to serve on the ranch, a job which includes being protective of its property, it is inclined to bark warnings about neighborhood activity, but it is not an obsessively barking dog.

The Aussie is intelligent, learns quickly, and loves to play. This means that a bored, neglected, unexercised Aussie will invent its own games, activities, and jobs, which to a busy owner might appear to be hyperactivity: for example, an Aussie may go from being at rest to running at top speed for several 'laps' around the house before returning to rest. Without something to amuse them, Aussies often become destructive. Aussies also do best with plenty of human companionship: they are often called "velcro" for their strong desire to always be near their owners and for their tendency to form intense, devoted bonds with select people. Recent studies have also shown that shepherds work well with special-needs kids and babies.
