The registration of working sheepdogs in South Africa is the responsibility of the South African Sheepdog Association. ISDS registered dogs imported into the country can be transferred onto the SASDA register. Dogs not registered can become eligible for registration by being awarded a certificate of working ability by a registered judge. Occasionally they will facilitate the testing of dogs used for breeding, for hip dysplasia and collie eye anomaly, to encourage the breeding of dogs without these genetic flaws.
Working border collies can take direction by voice and by whistle at long distances when herding. Their great energy and herding instinct are still used to herd all kinds of animals, from the traditional sheep and cattle, to free-range poultry, pigs, and ostriches. They are also used to remove unwanted wild birds from airport runways, golf courses, and other public and private areas.
