Cattle Dog is a shelter label more than a single breed. Most dogs carrying it are Australian Cattle Dogs, known as 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 by crossing collie-type herders with dingoes, creating a tough, compact drover that moves cattle by nipping their heels.
Most are medium-sized, muscular and short-coated, around 30 to 50 pounds, with plenty of stamina and a sharp mind. Many bond closely with their people, stay wary of strangers and want a job to do. In Glendale that job can be a morning trail, a training session or a puzzle toy. Mixes vary in size, coat and energy, so the dog in front of you tells you more than the label does.
