A House full of Hairless Dogs!

They have ruled the bedrooms of the Americas for 3000 years, as noble medicine dogs and hot water bottle substitutes, they have earned their throne. If you have a bed like this one, you must be a Xolo person living in a Xolo house. This is the bed in the master bedroom at Lizardhaven, and these are just a few of the inhabitant Xolo. Usually they are not allowed on the bed, but try and explain that to them.
