Because there are white patches on the forehead, which are similar to the filial piety worn by people, this kind of dog is called a filial piety dog. Folks generally believe that raising this kind of dog will bring bad luck and is a symbol of unlucky. However, in fact, this statement is a superstition, lacks scientific basis, and is not credible.

In any case, we should observe and understand the appearance and behavior of dogs with a scientific and objective attitude, while respecting different cultures and personal opinions and interpretations of dogs. Most importantly, give your dog enough love, care, and training to ensure their health and happiness.
