There is some truth to the idea that dogs hide from people with evil spirits. Dogs have very keen perception. They can sense the surrounding environment and human emotions through senses such as smell, vision, and hearing. Some people believe that dogs can sense people's auras and avoid people with strong or bad auras.
However, this view lacks science The evidence supports it, so it is not entirely certain. In addition, a dog may avoid a person because it senses that person's unfriendly or threatening behavior, not necessarily because it perceives the influence of the aura. In short, dog behavior is the result of a combination of factors and cannot be simply attributed to one reason.
