Folks believe that not only dogs are spiritual, but cats are also spiritual animals. It is said that cats have nine lives. When dogs or cats bark in the middle of the night in the village, people think there is something unclean, and then cats and dogs see it and remind people not to come out. They bark to drive away evil things.
Not only in the past, but even now, many people still love cats and dogs, because cats and dogs have a keen sense of smell, especially cats' eyes, which emit deep light at night, while dogs look after the home all day, and those sharp eyes seem to see everything. I believe many people have seen some horror movies on TV series, in which dogs played a role. Not only can they see those dirty things, but black dog blood can also drive away ghosts.
Moreover, some detective TV series will definitely have dogs, and they need to use their keen sense of smell to find clues. In the past, dogs were sacred animals. People usually erect two stone statues of dogs on both sides of the gate, which means to ward off evil spirits and keep peace. Those two stone dogs are mighty and brave, let alone ghosts. Other animals are afraid when they see them.
Therefore, people will take a dog with them when they move, because dogs are the most spiritual animals. The purpose is to let dogs go to their new homes first and make sure that there are no dirty things and safety hazards before people begin to live. If the dog refuses to enter or barks, people will leave immediately and will not move in.
Dogs have always been people's most loyal friends, no matter in the past, present or future. Many people like cats and dogs.
