The Dog (狗) is one of the 12-year cycle of animals that appear in the Chinese zodiac
The Great Race called by the Jade Emperor:
“An ancient folk story tells that Cat and Rat were both very bad at swimming.
Although they were poor swimmers, they were both quite intelligent. To get to the meeting called by the Jade Emperor, they had to cross a river to reach the meeting place. The Jade Emperor had also decreed that the years on the calendar would be named for each animal in the order they arrived to the meeting.
Cat and Rat decided that the best and fastest way to cross the river was to hop on the back of Ox.
