Historical information

Shepherding is among the oldest occupations, beginning some 5,000 years ago in Asia Minor. Sheep were kept for their milk, meat and especially their wool. Over the next thousand years, sheep and shepherding spread throughout Eurasia. Henri Fleisch tentatively suggested the Shepherd Neolithic industry of Lebanon may date to the Epipaleolithic and that it may have been used by one of the first cultures of nomadic shepherds in the Beqaa Valley.
Some sheep were integrated in the family farm along with other animals such as chickens and pigs. To maintain a large flock, the sheep must be able to move from pasture to another pasture. This required the development of an occupation separate from that of the farmer. The duty of shepherds was to keep their flock intact, protect it from predators and guide it to market areas in time for shearing. In ancient times, shepherds also commonly milked their sheep, and made cheese from this milk; few shepherds still do this today.
In many societies, shepherds were an important part of the economy. Unlike farmers, shepherds were often wage earners, being paid to watch the sheep of others. Shepherds also lived apart from society, being largely nomadic. It was mainly a job of solitary males without children, and new shepherds thus needed to be recruited externally. Shepherds were most often the younger sons of farming peasants who did not inherit any land. In other societies, each family would have a family member to shepherd its flock, often a child, youth or an elder who couldn't help much with harder work; these shepherds were fully integrated in society.
Shepherds would normally work in groups either looking after one large flock, or each bringing their own and merging their responsibilities. They would live in small cabins, often shared with their sheep, and would buy food from local communities. Less often shepherds lived in covered wagons that travelled with their flocks.
Shepherding developed only in certain areas. In the lowlands and river valleys, it was far more efficient to grow grain and cereals than to allow sheep to graze, thus the raising of sheep was confined to rugged and mountainous areas. In pre-modern times shepherding was thus centred on regions such as the Middle East, Greece, the Pyrenees, the Carpathian Mountains, Scotland and Northern England.

The Shetland Sheepdog, often known as the Sheltie, is a breed of herding dog that originated in the Shetland Islands of Scotland. The original name was Shetland Collie, but this caused controversy amongst Rough Collie breeders of the time, so the breed's name was formally changed. This diligent small dog is clever, vocal, excitable and willing to please. They are incredibly trustworthy to their owners to the point where they are often referred to as "shadows" due to their attachment to family. This breed was formally recognized by The Kennel Club (UK) in 1909.
Like the Shetland pony, Shetland cattle and the Shetland sheep, the Shetland Sheepdog is a hardy but diminutive breed developed to thrive amidst the harsh and meagre conditions of its native islands. While the Sheltie still excels at herding, today it is often raised as a working dog and/or family pet.

The Rough Collie (also known as the Long-Haired Collie) is a long-coated dog breed of medium to large size that, in its original form, was a type of collie used and bred for herding sheep in Scotland. More recent breeding has focused on the Collie as a show dog, and also companion. The breed specifications call for a distinctive long narrow tapered snout and tipped (semiprick) ears, so some dogs have their ears taped when young. Rough Collies generally come in shades of sable and white (sometimes mahogany), blue merle, tri-coloured, and colour-headed white.
There is a smooth-coated variety known as a Smooth Collie; some breed organisations, including both the American and Canadian Kennel Clubs, consider smooth-coat and rough-coat collies to be variations of the same breed. Rough Collies closely resemble the smaller Shetland Sheepdogs or "Shelties", but the two breeds do not have an exclusive linear relationship.
