Cattle Dog is a shelter label more than a single breed. Most dogs listed this way are Australian Cattle Dogs, called Blue or Red Heelers, or mixes with one, though Texas Heelers and crosses with Border Collies or Labs turn up too. 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 dense double coat that sheds moderately. They're intelligent, independent and often devoted to one person. In Gulfport, that means a dog that needs daily work in humid heat and rain, plus a secure yard or a dependable routine. Mixes vary in size, coat and energy, so watch how a dog behaves in person rather than relying on the label.
