The Australian Silky Terrier is a small breed of dog of the terrier dog type. The breed was developed in Australia, although the ancestral types and breeds were from Great Britain. It is closely related to the Australian Terrier and the Yorkshire Terrier. The breed is called the Silky Terrier in North America, but is called the Australian Silky Terrier in its country of origin and in the rest of the world.

The Australian Silky Terrier is a small and compact short-legged terrier, 23 to 26 cm (9.1 to 10.2 in) at the withers, alert and active. The long silky grey and white or blue and tan coat is an identifying feature, hanging straight and parted along the back, and described as "flat, fine and glossy". All proportions and aspects of the body and head as well as desirable shades of grey and white and placement of markings are extensively described in the breed standard.

The Silky Terrier should be slightly longer than tall (about one fifth longer than the height at withers). This is a dog that was historically used for hunting and killing rodents and snakes, so its body should have enough substance to fit this role. The coat requires quite a lot of regular grooming and shampooing to retain its silkiness.

The Silky Terrier has a strong, wedge-shaped head. The eyes are small and almond-shaped. According to the standards, light-colored eyes are considered a fault. The ears are small and carried erect. The Silky Terrier has a high-set tail and small, almost catlike, feet. The coat should be long, but not so long to approach floor length. The hair on the face and ears is normally cut.

The breed standard describe the ideal Australian Silky Terrier temperament as keenly alert and active. They love to be given chances to run and play, but must have a tightly fenced yard. They also enjoy brisk walks and playing ball. The Silky is able to do well in an apartment, although they are also an active indoor breed. It is important they are kept busy and social to discourage boredom. In a recent survey reported (on Dogs 101) of 91 small breed dogs (16 inches and under 22 lbs) the Silky Terrier was ranked in the top 20 in learning the quickest. The Silky Terrier is described as the best of both worlds temperament-wise. They love to sit on laps and do "toy dog" things[citation needed] but have an easy going more laid back Terrier personality ready for just about any activity.

The Silky Terrier's coat is highly susceptible to tangles and matting and requires daily brushing and combing. This breed requires a deep commitment from the owners. To keep the coat lustrous, regular shampooing is necessary. Using an Avocado and Oatmeal Shampoo will help alleviate the itchy, dry skin of this breed.
