A South Russian Ovcharka, also known as a Ukrainian Ovcharka or South Russian Sheepdog, is a large, long-haired (12 centimeters), white Livestock guardian dog. Breeders have not yet developed a precise theory of the dog’s origins. However, it is agreed that its ancestors lived in the Crimea region between the Black Sea and the Sea of Azov.Standing about 36 inches tall it has a long head, with dangling, small, triangular ears. Its coat consists of long, usually white (although sometimes white with yellow or with shades of grey), thick coarse hair, that is bushy and slightly wavy.An undemanding dog, it can adapt to most weather conditions.

The Southern Hound was a breed of dog that existed in Britain probably until sometime in the 19th century. The exact date of its extinction is not known; it is likely that it was gradually interbred with other breeds until the genuine Southern Hound bloodline ceased to exist.The origins of the Southern Hound are equally unclear. Most writers suggest that it is derived from the Talbot, which was a predominantly white, slow, deep-throated, scent hound, also of uncertain origin, though it is sometimes claimed that it came from Normandy. It is suggested that at some point the Talbot was crossed with Greyhounds to give them an extra turn of speed. However, in The Dog published in 1852, William Youatt states that the Southern Hound may have existed in Britain since ancient times rather than being brought from France by the Normans.The Southern Hound was a tall, heavy dog with a square head, and long ears. It had a deep chest, a long bony body and a deep melodious voice. It was a slow dog, but with excellent scenting abilities and was employed to follow the trail of the quarry during a hunt. Because of its lack of speed and deliberate nature, it was considered best used for hunting game such as hare or deer, which would eventually be exhausted by its relentless pursuit but, unlike a fox or rabbit, could not escape to the safety of a den or burrow. It was still common south of the River Trent in the 18th century. Further north the North Country Beagle or Northern Hound was favoured. This was a faster dog but probably lacked the delicate nose of the Southern Hound. In his The Dog, in Health and Disease in 1859, “Stonehenge” (the pen name of John Henry Walsh, editor of The Field (magazine)) says the two breeds could be differentiated by the large dewlap present in the Southern Hound, but the illustration of the Southern Hound in the same book lacks this detail. How far the Talbot, Northern Hound and Southern Hound were intermixed is impossible to ascertain: authors writing in the mid-19th century were already having difficulty distinguishing between the three breeds.The Southern Hound seems to have fallen out of favour during the 18th century as the fashion for shorter hunts led to the development of the faster Foxhound. Youatt wrote that there were still packs in use in Devon in the 19th century and that the Southern Hound was sometimes used in conjunction with Foxhound packs to help pick up the cold trail when the pack lost the scent. The famous bloodhound breeder Edwin Brough reported that in 1881 he used a pure bred Southern Hound, ‘Clara’, (pictured in this article) as a cross to his bloodhounds, and this outcross was bred on from into the modern population of bloodhounds.Many of the modern hound breeds are believed to have Southern Hound blood: Beagles, Harrier, Foxhounds, Coonhounds and Bloodhounds among others.

The Spanish Mastiff or Mastín Español is a large breed of dog originating in Spain originally bred to be a Livestock guardian dog and a guard dog whose purpose is to defend livestock from Gray wolf and other predators. The Mountain dog type has a heavier coat, and is more commonly exhibited at dog shows.

The Spanish Water Dog (Spanish language: Perro de Agua Español) is a breed of dog developed by shepherds in Spain as a multi-purpose herding dog. It was also used sometimes as a gundog, as well as an assistant to fishermen.

The Spinone Italiano is an Italian dog breed. It was originally bred as a pointing breed. To this day, the breed still masters that purpose. The Spinone is a loyal, friendly and alert dog with a close lying, wiry coat. It is an ancient breed that can be traced back to approximately 500 BC.It is traditionally used for hunting, pointing, and retrieving game (HPR), but, in addition to that purpose, the intelligent and strong Spinone may be practically anything ranging from a companion dog to an assistance dog.

The Sporting Lucas Terrier is a small breed of dog of the terrier type. The breed is named for Jocelyn Lucas.

The St. Bernard or St Bernard (/ˈbɜrnərd/ or /bərˈnɑrd/) is a breed of very large working dog from the Italian and Swiss Alps, originally bred for rescue. The breed has become famous through tales of alpine rescues, as well as for its enormous size.

The St. John’s water dog, also known as the St. John’s dog or the lesser Newfoundland, was a landrace (naturally occurring variety) of domestic dog from Newfoundland. Little is known of the types that went into its Genetics, although it was probably a random-bred mix of old English, Irish and Portuguese working dogs. The number of St. John’s water dogs started declining by the start of the 20th century. By the early 1980s, the breed was extinct.

The Stabyhoun or Stabij is a rare dog breed that just like the Wetterhoun originates from Friesland, a province in the North of the Netherlands. The first part of the name is probably from the Dutch: “sta me bij” (stand by me). The last part is simply Frisian, meaning dog, which is pronounced “hoon”. There are only approximately 3507 Stabyhouns in existence today.

The Staffordshire Bull Terrier (informally: Staffie, Stafford, Staffy or Staff) is a medium-sized, short-coated breed of dog. It is an English people dog, the fifth most popular breed, and related to the Bull Terrier. Descended from bull baiting ancestors, it is muscular and loyal.

The Standard Schnauzer is the original breed of the three breeds of Schnauzer, and despite its wiry coat and general appearance, is not related to the British terriers. Rather, its origins are in old herding and guard breeds of Europe. Generally classified as a working or utility dog, this versatile breed is a robust, squarely built, medium-sized dog with aristocratic bearing. It has been claimed that it was a popular subject of painters Sir Joshua Reynolds, Albrecht Dürer and Rembrandt, but actual proof remains elusive.

The Stephens Cur (aka 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 darkies” 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’s good for hunting raccoon and squirrel, but can also be used to bay wild boars. They are registered with the United Kennel Club, and the Continental Kennel Club.
