Foo dogs, also known as Fu lions or guardian lions, are traditional Chinese sculptures that resemble a lion. They are often placed at the entrances of buildings, temples, and homes to protect against negative energies and evil spirits. These statues typically come in pairs, with one representing the male and the other the female, symbolizing balance and harmony. The design of Foo dogs features intricate details, including a curly mane and a ball or cub under their paw, which signifies power and authority. They are commonly made from stone, bronze, or ceramic and are popular in various cultures beyond China, often seen in Asian art and architecture.
