Hades likes to play underneath blankets. I can't remember when this started, but one of Hades favourite games to play with people or dogs, is to scoot underneath a blanket, and mouth and yip and shriek like a wild banshee. If his head comes out and is exposed he'll either stop playing, or he'll readjust himself so his head is hidden again. He makes very weird noises, that he only makes when playing this way under the blanket. He is a WEIRD dog!
