In 1874, the American Field put together the Field Dog Stud Book and registry of dogs in the United States was born. This Field Dog Stud Book is the oldest pure-bred registry in the United States. At that time, dogs could be registered even when bred from sires and dams of different breeds. At about this time, the Llewellin Setter was bred using blood lines from the Lavarack breeding of English Setter and, among other breeds, bloodlines from native Irish Setters. Around the same time, the red Irish Setter became a favourite in the dog show ring.
