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. Originating in the 1800s, There is a smooth-coated variety known as a Smooth Collie; some breed organisations, including both the American and Canadian Kennel Clubs, consider the smooth-coat and rough-coat breeds to be variations of the same breed. Rough Collies closely resemble the smaller Shetland Sheepdog or 'Sheltie', but the two breeds do not have an exclusive linear relationship. Earlier dogs were also more sturdy in build and reportedly capable of covering up to 100 miles in one day. The dog needs to be gradually acclimated to the cold and a suitable insulated outdoor shelter must be provided for the dog along with ample quality food and a source of unfrozen water. The rough collie also relishes playing in the snow with children during the winter months.
