The breed is known by many other names: the Australian Cattle Dog, Blue Heeler and Hall’s Heeler. The Queensland Heeler was developed by crossing the Dingo-blue merle Collies, Dalmatians and black and tan Kelpies. A herding breed, the Queensland Heeler is known for its skill of snapping and biting at cattle’s heels. It weighs between 30 to 35 pounds and has a height range of 17 to 20 inches, with males generally heavier and taller than the females. It has a broad skull that flattens to a slight but pronounced stop. It has a black nose, eyes that are dark brown and oval in shape, and ears that are wide set and medium in size. Its tail hangs at a slight curve and held moderately low. The coat is made of double layers of smooth and dense hairs. Colours include blue, blue-mottled, red speckled or blue speckled with or without other markings.
The Queensland Heeler is a versatile working dog that is skilled in retrieving, herding, guarding, agility, competitive obedience and performing tricks. It is a highly intelligent breed that is happiest when given work to do. They are loyal, brave and obedient to their owner and family. They do have a dominant and willful streak and may be aggressive towards other dogs if not trained and socialized properly. They may also be reserved and suspicious of people and dogs they don’t know. They have a high level of energy and stamina so exercise should be an integral part of their daily routine. They can live for about 12 to 15 years.
