Yes, generally speaking, yellow dogs with white faces refer to dogs whose fur is mainly yellow and has white patches on their faces. This image is not uncommon in traditional Chinese culture and is often regarded as a symbol of good luck. For example, in some places, a yellow dog with a white face is considered a symbol of wealth, and people believe it can bring good luck and wealth.

However, this belief is not scientific. From the perspective of modern science, the color and patch distribution of dogs are determined by their genes and are not directly related to whether they can prosper the family. In other words, yellow dogs and white faces do not have any supernatural abilities. They are just ordinary animals like other dogs.
