Abstract
A pet boom rolls in Japan of recent years in the latter half of the 1980’s and it happens. Even only dogs and cats are reaching the number bred as a pet up to about 2684 numbers now. This figure is not very different from the number of 65-year-old or more senior citizen, and figure of the degree more than the total of less than 15-year-old child. However, it is a current state that development and the research of the universal design product that considers the pet are still scarce though it is such a society background. Then, to improve both QOL (Quality Of Life) and to improve it in both dogs and the people’s living for “Dog” bred a lot in the pet, the present study is proposed architectural and evaluated.
