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.
