Cattle Dog is a catch-all label. Most dogs listed this way are Australian Cattle Dogs, the Blue and Red Heelers, or mixes with one, though crosses with Border Collies, Labs and other breeds are common too. The original heelers were developed in nineteenth-century Australia to drive cattle over long distances by nipping at their heels, which explains the stamina and toughness.
Expect a medium, muscular dog of roughly 30 to 50 pounds with a short double coat, a sharp mind and a strong attachment to its people. Many are reserved with strangers and try to herd bikes, kids or other pets. That coat copes well with Rochester winters, but the brain still needs work, so training games and long outings matter as much as a yard. Mixes vary in size, coat and energy, so watch how each dog behaves.
