Foo Dogs Chinese, Bronze

I believe these are bronze Foo Dogs, they are 5" and 4 1/2" tall and 4" and 4 1/2" long, They weigh together 3.2 pounds. I bought them at auction because I liked them. I have no idea of there age or history. They looked special to me, one a little bigger than the other, There is it seems to be wax on one leg of one of them? I have no idea what this is about? (see photo laying on side), So any information would be helpful! I like them no matter if they are special or not, Sometimes you just feel good about buying something and go for it! I named them Vetraio and Bellin! Thanks for looking and any information about them would be appreciated!
