What exactly are the five elements of a dog?

If we only talk about native animals, we can divide them into five types. People born in JOE (1934, 1994) are wooden dogs, people born in Xu Bing (1946, 2006) are fire dogs, and people born in Wusu (688) also have the saying of sixty flowers. People born in JOE are the fire of Shantou's life, those born in Xu Bing are in the house, those born in the Reform Movement of 1898 are in the flat, and those born in Ren Xu are in the sea. But what exactly are the five elements? They must be earthy and dry, representing the northwest.
