This carved wooden netsuke depicts a dog in the refined miniature sculptural tradition of 19th century Japan, signed by the artist Masanao. Netsuke served as functional toggles for hanging containers from the sashes of kimono, yet were crafted with remarkable artistic attention to anatomical detail and expressive character. The piece exemplifies the Edo period's sophisticated appreciation for small scale carving and the cultural importance of these intimate objects within Japanese material culture.
