The Cardigan Welsh Corgi is the older of the two corgi breeds, developed in Cardiganshire, Wales, to drive cattle by nipping at heels and ducking kicks. It's long, low and heavier-boned than it looks, usually 25 to 38 pounds, with large rounded ears, a fox-like tail and colors that include blue merle and brindle.
Many Cardigans are loyal, steady and a little reserved with strangers. Their herding background shows up as alertness, barking and the occasional heel nip, and they respond well to patient, reward-based training. A thick double coat sheds heavily, and the long back needs protection from hard jumps and extra weight. In Tucson, that means regular walks, a cool indoor spot and paws kept off hot ground.
