There is a good chance that this is Shiwan pottery, and that it has some age, but I couldn't tell how old. Shiwan is a kiln that was (and is) specialized on figurines. Here is a page with a picture of another Shiwan Foo Dog. In Chinese they are called Lions, Foo Dog is used mainly in the west. Maybe another visitor of the site has more information...
