Antique Japan Crackle Glaze Celadon Dog Figure 1920

This is a rare made in Japan crackle glazed dog figure/bookend. It is a gorgeous green color with intentional all over crackle effect. The figure is of a dog with his paw on a ball. It is made of ceramic/ porcelain and looks to have a light almost cement filling to weight it. There are a couple glaze flaws but appear to be original imperfections.

I have researched this piece to the best of my ability and have found no others like this. I have been able to identify it by other similar figures using this technique and form.
