Question: Which dog, the Swedish Lapphund or the Scotch Collie, was used by the Sami people for herding and guarding their reindeer?

full_context: Document 1: Finnish Spitz: A Finnish Spitz (Finnish language: "Suomenpystykorva") is a breed of dog originating in Finland. The breed was originally bred to hunt all types of game from squirrels and other rodents to bears. It is a "bark pointer", indicating the position of game by barking, and drawing the game animal's attention to itself, allowing an easier approach for the hunter. Its original game hunting purpose was to point to game that fled into trees, such as grouse, and capercaillies, but it also serves well for hunting elk. Some individuals have even been known to go after a bear. In its native country, the breed is still mostly used as a hunting dog. The breed is friendly and in general loves children, so it is suitable for domestic life. The Finnish Spitz has been the national dog of Finland since 1979.
Document 2: Norwegian Buhund: The Norwegian Buhund is a breed of dog of the spitz type. It is closely related to the Icelandic Sheepdog and the Jämthund. The Buhund is used as an all purpose farm and herding dog, as well as watch dog and a nanny dog.
Document 3: Lapponian Herder: The Lapponian herder (Lapinporokoira or "Lapp Reindeer dog" or Lapsk Vallhund) is a breed of dog from Finland, one of three "Lapphund" breeds developed from a type of dog used by the Sami people for herding and guarding their reindeer.
Document 4: Icelandic Sheepdog: The Icelandic Sheepdog is a breed of dog of spitz type originating from the dogs brought to Iceland by the Vikings. It is of similar type to the Norwegian Buhund, the Shetland Sheepdog, and the Welsh Corgi. They are commonly used to herd sheep in the Icelandic countryside.
Document 5: Collie: The collie is a distinctive type of herding dog, including many related landraces and standardised breeds. The type originated in Scotland and Northern England. The collie is a medium-sized, fairly lightly built dog, with a pointed snout. Many types have a distinctive white pattern over the shoulders. Collies are very active and agile, and most types of collies have a very strong herding instinct. Collie breeds have spread through many parts of the world (especially Australia and North America) and have diversified into many varieties, sometimes with mixture from other dog types. Some collie breeds have remained as working dogs, used for herding cattle, sheep and other livestock, while others are kept as pets, show dogs or for dog sports, in which they display great agility, stamina and trainability. While the AKC has a breed they call "Collie", in fact collie dogs are a distinctive type of herding dog including many related landraces and formal breeds. There are usually major distinctions between show dogs and those bred for herding trials or dog sports. They typically display great agility, stamina and trainability and more importantly sagacity.
Document 6: Smooth Collie: The Smooth Collie is a breed of dog developed originally for herding. It is a short-coated version of the Rough Collie of Lassie fame. Some breed organisations consider the smooth-coat and rough-coat dogs to be variations of the same breed.

Document 9: Shetland Sheepdog: The Shetland Sheepdog, also known as the Sheltie, is a breed of herding dog. The original name of this breed was Shetland Collie, but this caused controversy among the Rough Collie breeders at the time, so the breed's name was formally changed to Shetland Sheepdog. This small dog is intelligent, vocal, excitable, energetic and willing to please and work hard. The breed was formally recognized by The Kennel Club in 1909.
Document 10: Scottish Terrier: The Scottish Terrier (also known as the Aberdeen Terrier), popularly called the Scottie, is a breed of dog. Initially one of the highland breeds of terrier that were grouped under the name of "Skye Terrier", it is one of five breeds of terrier that originated in Scotland, the other four being the modern Skye, Cairn, Dandie Dinmont, and West Highland White Terriers. They are an independent and rugged breed with a wiry outer coat and a soft dense undercoat. The First Earl of Dumbarton nicknamed the breed "the diehard". The modern breed is said to be able to trace its lineage back to a single female, named Splinter II.

The Norwegian Elkhound was first presented at a dog exhibition in Norway in 1877. It is one of the oldest dog breeds, and Elkhounds have been found buried in Viking burial grounds.

Document 12: Swedish Vallhund: The Swedish Vallhund, also known as the "Västgötaspets" and Swedish cow dog, is a breed of dog native to Sweden. The breed's name, "Vallhund", when translated into English, means herding dog, as the Swedish Vallhund was originally bred as a drover and herder of cows over 1,000 years ago. In 1942, the dog came close to extinction, but careful breeding and publicity by Swedish national Bjorn von Rosen and K. G. Zettersten managed to revive the breed in popularity and save it from its likely end. In 1943, the Swedish Kennel Club recognized the Swedish Vallhund as a breed, and officially categorized the Swedish Vallhund as "the Västgötaspets" for Västergötland, the province in which their revival took place. Since then, the breed has been recognized by, and bred in, over ten countries and has gained some popularity.
Document 13: Rough Collie: The Rough Collie (also known as the Long-Haired Collie) is a long-coated breed of medium to large size dog that in its original form was a type of collie used and bred for herding in Scotland. Originating in the 1800s, it is now well known through the works of author Albert Payson Terhune, and through the "Lassie" novel, movies, and television shows. There is also a smooth-coated variety; some breed organisations, including both the American and the Canadian Kennel Clubs, consider the smooth-coat and rough-coat dogs to be variations of the same breed. Rough Collies generally come in shades of sable, merles, and tri-coloured. This breed resembles a bigger version of the Shetland Sheepdog.

Other ancestors include the Gordon and Irish Setters.
