These are not lions....these are called 'foo dogs'. Foo Dogs are the ancient sacred dogs of Asia who guard Buddhist temples. The association between these dogs and Buddha is one of great significance. Foo Dogs have the appearance of a lion. The lion in Buddhist religion is seen as sacred, and has sometimes been offered to Buddha as a sacrifice. The name given to these guardians originates from China. The Chinese word for Buddha is Fo, which led to the original title– “Dog of Fo”. There have been other theories that the name developed from the city of Foochow; however, there is no actual proof of this. Another name given to the beast is “Lion of Korea”. This, of course, is due to the creatures close appearance to a Lion.
