Cattle Dog is a label rather than a single breed. In Tyler listings it most often means an Australian Cattle Dog, the Blue or Red Heeler, or a mix with one, though Texas Heelers and crosses with Border Collies or Labs can carry the name too. The Australian Cattle Dog was developed in nineteenth-century Australia, where collie-type herders were crossed with dingoes to make a tough drover that moves cattle by nipping at their heels.
Most dogs under this label are medium-sized and muscular, with a dense short double coat, plenty of stamina and a sharp, independent mind. Many bond tightly with one family, stay reserved with strangers and need a job, whether that's training games, long hikes or fetch. Mixes vary in size, coat and energy, so how a dog actually behaves tells you more than the label does.
