Two dogs sleep in my bedroom at night. There are two dog beds in there. One is an expensive orthopedic bed measuring about 36" x 26" The other is a cheap fluffy rectangle with 3 sides and measures about 18" x 14" One dog weighs 12 lbs. and is maybe 14" long One dog weighs 55 lbs. and is maybe 36" long Where does each dog sleep? Why? Riche
