Cattle Dog is a shelter label more than a single breed. Most dogs listed this way are Australian Cattle Dogs, the Blue and Red Heelers, or mixes with one, though Texas Heelers and crosses with Border Collies or Labs turn up too. The original breed was developed in nineteenth-century Australia to drive cattle by nipping at their heels.
Expect a medium, muscular dog, usually 30 to 50 pounds, with a short double coat that sheds moderately and more heavily in spring and fall. Many bond closely with one family, stay reserved with strangers and need a job. In Springfield, that job can be a daily neighborhood loop, a long leashed walk in Forest Park or training games at home. Mixes vary in size and energy, so watch how a dog actually behaves rather than relying on the label.
