The appearance of a yellow dog with a white face when it grows up mainly depends on its genetics. Generally speaking, the coat colors of yellow dogs with white faces are mainly divided into two types: yellow and white. The yellow part is usually distributed on the head and back, while the white part mainly appears on the face and legs.

However, it is worth noting that the coat color of yellow dogs with white faces does not necessarily remain the same. With age and changes in the environment, the color of the yellow dog's white-faced coat may change. For example, the white face of some yellow dogs may appear darker yellow when they are young, but as they grow older, their coat color may gradually lighten and eventually turn white.
