To prevent the problems of walking the dog, we separate the pathway of the owner and the pet. The pet can drown anywhere in their area, and the excreta can be used as nutrition. In the pet area, we provide several kinds of facilities for the pets to play around in which are providing exercises for their health at the same time.This type of soil decomposes fungus in twice the speed of normal soil, therefore the smell and bacteria from the fungus can be decomposed quickly.The soil turns the excreta to nutrition, which benefits a large area of soil, and the plants will grow better.
