The Australian cattle dog is of moderate build, enabling it to combine great endurance with bursts of speed and the extreme agility necessary in controlling unruly cattle. It is sturdy and compact, slightly longer than it is tall. Its gait is supple and tireless, and it must be capable of quick and sudden movement. Its ability to stop quickly is aided by the rudderlike action of its tail (which is never docked). Its weather-resistant coat consists of a short, dense undercoat and moderately short, straight outer coat of medium texture. Learn more!
