The “Patagonian Sheepdog” is a local working dog breed that was produced by selection from European working sheepdogs that arrived in the Magallanes region of southern Chile in the late nineteenth and early twentieth centuries. Currently, the Patagonian Sheepdog is most commonly found in the Chilean Patagonian region (43°12’ S to 56°30’ S), where it plays a fundamental role as a working dog in sheep and, to some extent, in cattle farming. Dog types that may have contributed to the Patagonian Sheepdog include the Old Welsh Grey and other old UK herding dogs. The modern Patagonian Sheepdog has been selectively bred by local sheep farmers to produce a herding dog that is well adapted to the area: a medium body size, long or semi-long fur, drooping or semi-erect ears, a docile character, and a great aptitude for sheep herding. Morphological studies have determined the body measurements, zoometric indices, coat color, and marking for Patagonian Sheepdogs. The objective of this investigation was to collect historical information related to the presence of this dog in Chilean Patagonia, providing general aspects of the morphology and behavior, all key factors for the recognition and conservation of this little-known herding dog.

Background We assess the putative identity of canids accompanying the Patagonian and Fuegian aborigines through an iconographic timeline encompassing 1699–1894, when a number of narratives provided written descriptions and illustrations of those aborigines and their canids. We determine what type of “dogs” were those canids, disentangling their type or breed group, to reveal their characteristics, composition, and development during that period. Methods We searched for illustrations published by navigators and explorers where the presence of canids was reported in the historical territory of the Patagonian aborigines (Aónikenk, Kawésqar, Manek'enk, Sélk'nam, and Yahgan). We constructed a matrix to record the descriptions of all canids represented in those illustrations. Their characterization included body size, coat, tail, ears, skull, and attitude, among others. We then classified whether they were morphologically closer to domestic dogs or to foxlike canids. We used the morphological appearance of dogs to classify them into breed types, whenever possible. Results and discussion We identified and classified 61 canids from 26 illustrations in accounts published between 1699 and 1894. From a historical perspective, those accounts suggest that soon after the first contacts with Europeans, the Patagonian and Fuegian aborigines began to exchange and breed dogs of non-native origin, initiating an extended process of mixing between aboriginal foxlike canids and European dogs. From a cynological perspective, the foxlike canids associated with the aborigines were widely present only before 1833, exhibing an homogeneous appearance with a solid coat, pointed snout, small erect ears of high insertion, and fallen and bushy tail. After 1833, the canids depicted show a more varied appearance and mixed coat, with blunter snout, drooping ears at lower insertion, and erect fine tail with sparse hair. Most of these were hunting dogs morphologically similar to modern breeds such as pointers/setters, hounds, terriers, and retrievers.

Patagonian sheepdog: Genomic analyses trace the footprints of extinct UK herding dogs to South America

Most modern dog breeds were developed within the last two hundred years, following strong and recent human selection based predominantly on aesthetics, with few modern breeds constructed solely to maximize their work potential. In many cases, these working breeds represent the last remnants of now lost populations. The Patagonian sheepdog (PGOD), a rare herding breed, is a remarkable example of such a population. Maintained as an isolated population for over 130 years, the PGOD offers a unique opportunity to understand the genetic relationship amongst modern herding breeds, determine key genomic structure of the founder PGOD populations, and investigate how canine genomic data can mirror human migration patterns. We thus analyzed the population structure of 159 PGOD, comparing them with 1514 dogs representing 175 established breeds. Using 150,069 SNPs from a high-density SNP genotyping array, we establish the genomic composition, ancestry, and genetic diversity of the population, complementing genomic data with the PGOD’s migratory history to South America. Our phylogenetic analysis reveals that PGODs are most closely related to modern herding breeds hailing from the United Kingdom. Admixture models illustrate a greater degree of diversity and genetic heterogeneity within the very small PGOD population than in Western European herding breeds, suggesting the PGOD predates the 200-year-old construction of most pure breeds known today. We thus propose that PGODs originated from the foundational herding dogs of the UK, prior to the Victorian explosion of breeds, and that they are the closest link to a now-extinct population of herding dogs from which modern herding breeds descended.
