Cattle Dog is a label more than a single breed. Most dogs listed this way are Australian Cattle Dogs, also called Blue or Red Heelers, or mixes with one, and the name can also cover Texas Heelers and crosses with Border Collies or Labs. The Australian Cattle Dog was developed in nineteenth-century Australia to drive cattle over long distances by nipping at their heels.
Expect a medium, muscular dog of roughly 30 to 50 pounds with a short double coat, a sharp mind and a strong need for a job. In Decatur, that job can be a daily loop through Legacy Park or a puzzle toy on a rainy afternoon. Mixes vary in size, coat and energy, so watch how each dog behaves rather than relying on the label.
