When the teacup Shunsuke dog grows up, its appearance is basically similar to that of the Pomeranian dog, with some unique characteristics.

First of all, its head is relatively round, and its face appears more rounded due to the shape and trimming. The ears are small and thick, with a short distance between the two ears, longer on the outside and shorter on the inside, with a little fluff at the root. The eyes are round, the pupils are generally black, and the nose is slightly larger and black. The mouth is slightly protruding, and after hair trimming it looks less pointed.

Secondly, the hair color of a Teacup Shunsuke is also a notable feature. The hair on the eyes and back is usually brown, while the hair on the mouth and belly is white. It should be noted that due to its long hair, the dog needs to be groomed and trimmed frequently, which can also help it reduce the amount of hair shedding during the change of seasons.

In addition, the Teacup Shunsuke is very small and relatively light, making it ideal for living in a limited space, such as an apartment or small home. Despite their small size, Teacup Shunsuke dogs are relatively intelligent and easy to train.

To sum up, the teacup Shunsuke dog will be cute, compact, and smart when it grows up, but it will also require more attention and care from the dog owner.
