There is another version of the origin: the ancestors of long-haired dogs were probably imported from Iceland, presumably in the 17th century. There is no exact information on how the formation of the breed took place.
Collies are known to have been used as herding dogs. They lived in large numbers in the highlands – the border area between Scotland and England.
The Rough Collie of the time is a medium-sized dog with thick, long hair that protects against harsh weather conditions.
