I love a good orthopedic memory foam bed as much as the next person. But right now, that fluffy cloud is acting like a fur coat on a furnace.
Pull out a flat sheet or a cotton towel and lay it on the floor. Bonus points if it’s a tile or hardwood floor that stays naturally cool. Your dog will think you’ve invented a magic carpet.
If your dog insists on sleeping on the couch, throw a cooling pad (the gel kind you can get at any pet store) over the cushion. It’s like giving them a personal air conditioner they can drool on.
