This Blue Heeler gets its name because it nips at the heels of animals as it corrals them. What is the more formal name of this breed?

The Australian Cattle Dog, or ACD, typically has two coat colors: red and blue. ACDs with dark or light brown coats do exist, but are considered to be faults. The ACD is known for its agility and ability to herd cows quickly and efficiently.
