To solve a conventional problem that there are nothing but photographs and videos (both having two-dimensional planes) from life of memories as an object for filling, comforting and curing the deep sorrow, sadness and sense of loss of a keeper who lost a pet dog.

This dog memorial is a dog-shaped doll (a three-dimensional solid with a form and color) closer to the actual figure of the pet dog than the photograph and the video, the dog memorial is cremated with the body of the pet dog, the soul of the dog is shifted thereto and the dog memorial left in the bones and ashes is brought back home and kept close to the keeper. The pet keeper thus emotionally connects this memorial to the soul and memories of the pet dog and thinks it as the "reincarnation" of the pet dog, and the deep sorrow, the sadness and the loss of the pet keeper are filled, comforted and cured.
