The Foo Dogs, in Chinese tradition, stand for protection. They are protective symbols. They basically protect whatever and whomever they are guarding from negative energy and bad thoughts. Only good thoughts and positive chi can function in their territory.
1. What is it good for - This symbol of feng shui is good for promoting positive chi within a house or a room. It can be used to remove negativity and smooth completion of tasks that have been started.
2. Where to keep it - The foo dogs should only be bought in twos. They can be put outside the house or the office, as guardians. They should be kept at a high position, especially when they are put right outside the front door.
