They needed dogs that could flush game, pull down the larger wounded game, and guard their farms against prowlers and wild animals at night.
The farmers also needed a dog that could withstand the rigors of the African bush, handle the drastic changes in temperature from the heat of the day to the freezing night temperatures, be short-coated to avoid ticks in the brush, and that could go 24 hours without water.
This dog also had to be a companion and protector to his wife and children.
