My father-in-law received a ceramic dog for a gift. It is about 12" high and complete sealed so you cannot look into the cavity. A short time ago he fell against this dog and broke one of its ears off. Inside the cavity were about 20 little ceramic birds about 3/4" long and either white, yellow or brown in color. These little birds have a fair amount of detail. The tag says the statue was made in China.
The question is what in the heck is going on here? What significants do the bird have? It is obvious the little birds were put in the dog right after it was cast as some of the birds are stuck to the interior surface of the casing.
