“Breeching” refers to the long and thick hair on the outside rear of a dog’s thighs (but not below its hock joints). Several breeds have breeching: Alaskan Malamutes and American Eskimo Dogs, for example. But when we mention breeching along with the description, “It’s weather resistant outer coat is kind of short, straight and with medium texture and a short dense undercoat,” it has to be the Australian Cattle Dog.
