Modern dogs are descendants of Asian wolves. They are notorious in much of the Europe because of their cunningness, cruelty, stealth and occasionally – evil and demons. The Indians named the famous Mongolian warrior Genghis Khan, because of his brutality, a ‘wolf’. However, a Norse legend considers ‘wolves’ as sacred animals and the Romans even venerated them. Therefore, a wolf tattoo can be associated with anything depending upon with culture you allow your tattoo to interpret.
