The Australian Terrier is a small breed of dog of the terrier dog type. The breed was developed in Australia, although the ancestral types of dogs from which the breed descends were from Great Britain.
The Australian Terrier is a small dog with short legs, weighing around 6.5 kilograms (14 lb) and standing about 25 centimeters (9.8 in) at the withers, with a medium length shaggy harsh double coat that is not normally trimmed. Fur is shorter on the muzzle, lower legs, and feet, and there is a ruff around the neck. The coat colors are blue or silver and tan with a lighter colored topknot, and with markings on face, ears, body, and legs of a color described in the breed standard as "tan, never sandy", or a solid red with a sandy variation. The tail was traditionally docked, in order to protect the dog from spinal injury while working and hunting in the field. As with most pet dog breeds, all proportions and aspects of the body and head, as well as colours and markings, are extensively described in the breed standard.
