The Dog seems to be the 11th of all creatures of the Constellations. The Ruler of Jade said according to one story that the direction of their arrival at his house would be chosen. In another nation, rooster, monkey, and dog helped a god overcome wicked minds. Then they went together into the group. The Ruler of Jade walked by the direction they encountered in another nation since they came at the very same moment. So Dog was on the 11th position.
