Inugami are explained to be raised in the storage room chests (tansu), under the floors, and in the water jugs of the families that have inugami.
In the legends of Komatsu, Shūsō District, Ehime Prefecture (now part of Saijō), there were as many inugami as there were people in families that had inugami, and the number of inugami increased each time the family grew larger.
