How did blue heelers get their name?

Blue Heelers, also known as Australian Cattle Dogs, got their name due to their distinctive blue or mottled coat and their herding behavior. The term "heelers" refers to their working style of nipping at the heels of cattle to drive them. The breed was developed in Australia in the 19th century, primarily from a mix of various herding dogs, including the Blue Merle Collie and the Dingo. Their name reflects both their appearance and their role as effective herding dogs.
