The record for the most expensive sheepdog has been broken by a 12-month-old female red-and-white border collie called Kim. She sold for £28,455 ($38,893; including buyer's premium) at an online auction organized by Farmers Marts in Dolgellau, Gwynedd, Wales, UK, on 3 February 2021.

A sheep dog or sheepdog is generally a dog or breed of dogs historically used in connection with the raising of sheep. These include livestock guardian dogs used to guard sheep and other livestock and herding dogs used to move, manage and control sheep and other livestock.

As the name suggests, herding breeds were developed to gather, herd, and protect livestock such as sheep or cattle. That shared heritage means they all have the instinctive skill and drive to control the movement of other animals.
