This will be the third anime based off of the manga, Itoshi no Muco or Lovely Muco in English, by Takayuki Mizushina. It is a simple slice of life manga and the anime is very much the same. You can see the synopsis and trailer after the break.

The anime depicts the life of the pet dog Muco and his owner Komatsu, who lives in his glass-making workshop in the mountains.
