Watching Dagon play with the orange squeaky monkey, I've started wondering if he personifies (or dogifies?) it in the same way a human would.
He does seem to treat it more like a creature than a toy, bringing it with him when he travels between rooms, and cuddling with it in bed. He also carries it with him when he pokes his head through the blinds, checking the coast is clear. And as of a few days ago, he has taken to leaving it on the window sill, as if the monkey has been assigned to keep watch on his behalf.
What a weird dog.
