"The general belief is that an inugami is created by tying a dog and placing a bowl of food just out of its reach. It would take days for the dog to die, and during this time the dog's master would tell it that its pain is nothing compared to his own. The onmyouji then follow some secret black magic rituals. When the dog dies, it become an inugami; since its dying wish would have been to eat, the food placed around the corpse would act as a placatory offering, and thus make the spirit obedient. The ghost-dog is then used as weapon to scare to death the enemies of the dog's master. Inugami are, by any account, terrible and wrathful, fearful and powerful. Only an experienced and prepared onmyouji may ever attempt to control one successfully." © Monstropedia
