Australian cattle dog is a breed of dog that originated in Australia during the 1800’s. It was developed from several breeds of farm dogs, including collies and kelpies. Farmers and ranchers use Australian cattle dogs to herd cattle. These dogs nip at the heels of the cattle to keep them from straying. The dogs also make excellent watchdogs and affectionate pets.
Australian cattle dogs stand from 17 to 20 inches (43 to 51 centimeters) high and weigh 35 to 45 pounds (16 to 20 kilograms). They have short, thick coats and bushy tails. Many of the dogs are blue and may have black, blue, or tan markings on the head, and tan markings on the chest and legs. Others are red, and many have red speckles all over the body. Puppies are born with white coats. Their color and markings appear in a few months. The Australian cattle dog has been known by several other names, including the Australian heeler, the Queensland heeler, the Queensland blue heeler, and the blue heeler.
