We saw our dog Jessica jump on the water trough and thought she would be soaking wet, just to find out it was frozen. My husband then picks her up to film the video to show the frozen water where the sheep normally would come to drink on the farm. South Africa faced the coldest day in four years and the joint second coldest day in nine years. We don't receive snow across entire South Africa during the winter. Certain places when the water troughs for the animals start to freeze we see it as very cold weather. A watering trough (or artificial watering point) is a human-made or natural receptacle intended to provide drinking water to animals, livestock on farms or ranches, or wild animals.
