My friend has dog ghosts in his house. He does not feel haunted he says. One can surmise that dog ghosts have no envy. In life dogs only wanted what was coming to them. In life a dog has appetite, wishes, tall grass, clotted fragments, serviceable memories, instincts, and fast dreams. But no vituperative ideas. The latter may belong to the cat ghosts. The dog spirits aren't saying. They are stretched out in the sunbeams in what we know is a very real house.
