Cattle Dog is a label more than a single breed. It most often points to an Australian Cattle Dog, the Blue or Red Heeler, or a mix with one, though Texas Heelers and crosses with Border Collies or Labs also turn up. The Australian Cattle Dog was developed in nineteenth-century Australia to drive cattle over long distances by nipping at their heels.
Most are medium-sized, muscular and short-coated, around 30 to 50 pounds, with a double coat that sheds moderately. They're sharp, loyal and often reserved with strangers, and they want a job. In Baton Rouge that job might be a morning run, a fetch session or a trick-training game indoors when the afternoon heat builds. Mixes vary in size, coat and energy, so a dog's own behavior says more than the label.
