Question: Which dog is larger, the Alpine Mastiff or the Mountain Cur?

full_context: Document 1: Karelian Bear Dog: The Karelian Bear Dog (KBD) is a Finnish or Karelian breed of dog. In its home country, it is regarded as a national treasure. KBD will hunt a variety of animals. Its quick reflexes and fearless nature have made it very popular for hunting aggressive game, including bears, moose, and wild boar. It was the breed's ability to hunt and offer protection against a bear that earned the breed its name.
Document 2: Alpine Spaniel: The Alpine Spaniel is an extinct breed of dog which was used in mountain rescues by the Augustinian Canons, who run hospices in the region around the Great St. Bernard Pass. The spaniel was a large dog notable for its thick curly coat. One of the most famous specimens of the Alpine Spaniel is Barry, however his preserved body has been modified on more than one occasion to fit with descriptions of the extinct breed from earlier time periods. Due to the conditions in the Alps, and a series of accidents, extinction was discussed as a possibility by authors during the 1830s, and at some point prior to 1847 the entire breed was reduced to a single example due to disease. Evidence held at the Natural History Museum in Bern show that two distinct breeds of dog were being used in the area during this time period. The breed is thought to be the predecessor to the modern St. Bernard and the Clumber Spaniel.
Document 3: Treeing Cur: The Treeing Cur is a breed of dog that originated in the mid-west and was first recognized by United Kennel Club on November 1, 1998, due to the efforts of Alex and Ray Kovac. "Most Cur breeders were not well off and so they required a dog that could serve multiple purposes: hunter, guardian, and stock dog. The result was the Treeing Cur, "which is the most varied in size and colors of the Cur breeds", according to United Kennel Club.They are primarily used to tree squirrels, raccoons, opossums, wild boars, bears, mountain lions and bobcats as well as to hunt big game.
Document 4: Bernese Mountain Dog: The Bernese Mountain Dog (German: "Berner Sennenhund" ) is a large-sized breed of dog, one of the four breeds of Sennenhund-type dogs from the Swiss Alps. The name "Sennenhund" is derived from the German "Senne" ("alpine pasture") and "Hund" ("dog"), as they accompanied the alpine herders and dairymen called "Senn". "Berner" (or "Bernese" in English) refers to the area of the breed’s origin, in the canton of Bern. This mountain dog was originally kept as a general farm dog. Large Sennenhunde in the past were also used as draft animals, pulling carts. The breed was officially established in 1907. In 1937, the American Kennel Club recognized it; today, the club classifies it as a member of the Working Group.
Document 5: Bullmastiff: The Bullmastiff is a large-sized breed of domestic dog, with a solid build and a short muzzle. The Bullmastiff shares the characteristics of molosser dogs, and was originally developed by 19th-century gamekeepers to guard estates. The breed's bloodlines are drawn from the English Mastiff and the extinct Old English Bulldog. It was recognized as a purebred dog by the English Kennel Club in 1924. They are quiet dogs and very rarely bark.
Document 6: Stephens Cur: The Stephens Cur (a.k.a. Stephens' Stock Cur), is a scent hound that belongs to the Cur dog breed. They were originally bred by the Stephens family in southeastern Kentucky. The dogs known as "Little black dog" were bred by generations of that family for over a century. In 1970, they were recognized as separate and distinct breed of Cur. The dog is mostly black with white markings, but more than a third white is not permissible. It is good for hunting raccoon and squirrel, but can also be used to bay wild boar. They are registered with the United Kennel Club
Document 7: Coonhound: The coonhound is a type of scent hound and a member of the hound group. They are an American type of hunting dog developed for the game animals and working conditions found in the United States, specifically coon hunting. There are six distinct breeds of coonhound.
Document 8: Catahoula Cur: The Catahoula Cur is an American dog breed named after Catahoula Parish, Louisiana, United States. Also known as the Catahoula Leopard Dog, it became the state dog of Louisiana in 1979. The breed is sometimes referred to as the "Catahoula Hound" or "Catahoula Leopard Hound" because of its spots, although it is not a true hound but a cur. It is also called the "Catahoula Hog Dog", reflecting its traditional use in hunting wild boar.
Document 9: Greater Swiss Mountain Dog: The Greater Swiss Mountain Dog (German: "Grosser Schweizer Sennenhund" or French: "Grand Bouvier Suisse" ) is a dog breed which was developed in the Swiss Alps. The name "Sennenhund" refers to people called "Senn" or "Senner", dairymen and herders in the Swiss Alps. Greater Swiss Mountain Dogs are almost certainly the result of indigenous dogs mating with large mastiff types brought to Switzerland by foreign settlers. At one time, the breed was believed to have been among the most popular in Switzerland. It was assumed to have almost died out by the late 19th century, since its work was being done by other breeds or machines, but was rediscovered in the early 1900s.
Document 10: English Mastiff: The English Mastiff is a breed of extremely large dog (often known simply as the Mastiff) perhaps descended from the ancient Alaunt and Pugnaces Britanniae, with a significant input from the Alpine Mastiff in the 19th century. Distinguishable by enormous size, massive head, and a limited range of colours, but always displaying a black mask, the Mastiff is noted for its gentle and loving nature. The lineage of modern dogs can be traced back to the early 19th century, but the modern type was stabilised in the 1880s and refined since. Following a period of sharp decline, the Mastiff has increased its worldwide popularity. Throughout its history, the Mastiff has contributed to the development of a number of dog breeds, some generally known as Mastiff-type dogs, or, confusingly, just as "Mastiffs".
Document 11: Mastiff: Mastiff type means a large molosser dog. The term "mastiff type" has been used synonymously with the term "molosser". For example, the bulldog breeds, the Great Dane, the mountain dogs, the pit bulls and even smaller dogs such as the Boston terrier, may be considered "mastiff types" in this broad sense. The descriptive term, mastiff type, should not be confused with the breed, the Mastiff. All breeds are individual and should be referred to by their breed name to ensure correct identification.
Document 12: Montenegrin Mountain Hound: The Montenegrin Mountain Hound is a rare dog breed from the mountain regions across the Balkans. Black and tan, with a smooth coat, the Montenegrin Mountain Hound was called "Black Hound" in the past. The breed is of the same origin as the other Balkan hounds. He stands 18 to high and weighs 44 to . The breed is used to hunt fox, hare, and small game, occasionally hunting larger animals such as deer or even wild boar.
Document 13: Mountain Cur: The Mountain Cur is a type of working dog that is bred specifically for treeing and trailing small game, like squirrel and raccoons. They are also used for hunting and baying big game like bear and wild boar as well as being an all-purpose farm dog. Curs are a member of the Hound group, and the Mountain Cur is one of several varieties of cur. It can also be used as a water dog. Mainly bred in Ohio, Kentucky, Virginia, and Tennessee, it has been registered with the United Kennel Club since 1998. The Mountain Cur Breeder's Association was formed in 1957.
Document 14: Dogue de Bordeaux: The Dogue de Bordeaux, Bordeaux Mastiff, French Mastiff or Bordeauxdog is a large French Mastiff breed—and one of the most ancient French dog breeds. A typical brachycephalic molossoid type breed, the Bordeaux is a very powerful dog, with a very muscular body. This brawny breed has been put to work in many different capacities, from pulling carts and hauling heavy objects, to guarding flocks and, historically, the castles of the European elite.
Document 15: Alpine Mastiff: The Alpine Mastiff is an extinct Molosser dog breed, the progenitor of the St. Bernard, and a major contributor to the modern Mastiff (through such dogs as "Couchez"), as well as to other breeds that derive from these breeds or are closely related to them. M.B. Wynn wrote, "In 1829 a vast light brindle dog of the old Alpine mastiff breed, named L'Ami, was brought from the convent of Great St. Bernard, and exhibited in London and Liverpool as the largest dog in England." William Cavendish, 5th Duke of Devonshire, is believed to have bred Alpine Mastiffs at Chatsworth House.
