The Romanian Mioritic Shepherd Dog is a large breed of livestock guardian dog that originated in the Carpathian Mountains of Romania.
The Rottweiler is a large size breed of domestic dog. The dogs were known as ” butchers’ dogs” because they were used to herding dog livestock and pull Dogcart (dog-drawn) laden with butchered meat and other products to market.The Rottweiler was employed in its traditional roles until the mid-19th century when railways replaced droving for herding livestock to market. While still used in herding, Rottweilers are now used as search and rescue dogs, as guide dogs for the blind, as guard dogs or police dogs, and in other roles.
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 is very similar to the smaller Shetland Sheepdog which is partly descended from the Rough Collie.
The Russell Terrier is a predominantly white working terrier with an insatiable instinct to hunt formidable quarry underground. The breed was derived from the Reverend John Russell’s fox working terrier strains that were used in the 19th century for fox hunting. The Reverend’s fox working strains were much smaller than the Show Fox Terrier and remained working terriers. The size of the Russell Terrier (10? to 12?) combined with a small flexible, spannable chest makes it an ideal size to work efficiently underground. Their unique rectangular body shape with the body being of slightly longer length than the leg makes them distinctly different from the Parson Russell Terrier and the JRTCA Jack Russell Terrier.The Russell Terrier originated in England with Australia being designated as the country of development.
The Russian Spaniel is a type of spaniel first standardised in 1951 in the Soviet Union after World War II by cross breeding English Cocker Spaniels, English Springer Spaniels and other spaniel breeds. Physically it is similar to a Cocker Spaniel, but has a shorter, tighter coat and a longer body. Developed and used as hunting dogs, this breed does not suffer from any major health complaints other than those normally associated with spaniels. Popular in its native Russia, the breed was only introduced overseas in the 1990s, and is not yet recognised by any major kennel clubs.

The Russian Tracker or Russian Retriever is an extinct breed of domestic dog. It is uncertain when precisely the breed ceased to exist; it could still be found in the late 1800s. The Tracker was of Asiatic Russian origin. It was used for hundreds of years to protect and herd the flocks of the Indo-Aryan peoples people in the wind-beaten, snow-swept Caucasus Mountains. The Tracker was a large dog, sometimes standing as high as 76.2cm at the shoulder and weighing 45.4kg or more. Despite his seemingly cumbersome proportions, he was fast and flexible enough to chase off wolves and other such predators that threatened his sheep. He wore a thick, taffy colored double-coat that protected him from both the harsh weather and the savage wildlife. Aside from his physical prowess, this mountain dog was also blessed with exceptional intellect. He was so wise and capable (legend says) that he could keep himself and his flock alive and well for months on end with no human help. The breed is related to on some level, and may be synonymous with, the “Yellow Russian Retriever”, which measured 71.1cm and 40.8kg. That breed was reputed to be used for tracking wounded deer. however, the Flat-coated Retriever and a few of the Setters are also believed to carry Tracker blood.
The Russian Toy (also in Russia called the Russkiy Toy, Russian: Русский той) is a very small breed of dog originally bred in isolation in Russia from the English Toy Terrier which is known today as the Manchester Terrier. There are two types, smooth haired/coated and long haired, which were known by a variety of different names until brought together under the same standard as the Russkiy Toy in 2000. The breed was nearly wiped out twice; first following in the 1920s with the rise of Communism due to the toy dog’s traditional link to the aristocracy and secondly in the 1990s with the influx of foreign breeds following the fall of the Iron Curtain. The smooth haired type is the older of the two, with the long haired type first appearing in 1958.
Russo-European Laika (Russko-Evropeïskaïa Laïka) is the name of a breed of hunting dog that originated in the forested region of northern Europe and Russia, one of several breeds developed from landrace Laika (dog breed) dogs of very ancient Spitz Dog type. The Russo-European Laika itself dates to a breeding program begun in 1944 by E. I. Shereshevsky of the All-Union Research Institute for the Hunting Industry, in Kalinin (now Tver Oblast) Province.
