The Australian Cattle Dog (or ACD) also known as the Australian Heeler or Cattle Dog, was originally bred in New South Wales, Australia by Thomas Hall, a cattle farmer who bred dogs and dingoes he had tamed to produce a new canine breed that later became known as Halls Heelers. Later on, other Australian breeders started cross-breeding dingoes with other popular breeds like Collies, Dalmatians and Kelpies. The ACDs are identified on the basis of their coloring, and labeled as either a "Red Heeler" or "Blue Heeler". Australian Breeders of the ACD have also categorized the breed as either from New South Wales or Queensland based on their geographical origins.
As a cattle herder, the ACD is known as the workhorse among cattle farmers. Its agility, strength and courageousness allow it to easily control and move cattle in both open and confined spaces, enabling farmers to take care of large herds.
ACDs love wide open spaces to run, work and play while being watchful of strangers. They look after those they consider to belong in their pack while seeking direction from the owner as the pack leader.
The ACD isn't a high maintenance when it comes to keeping its appearance. Its smooth, short coat require only occasional bath and brushing to keep its coat clean and healthy.
