My dog loves to bury herself under our comforter.  We don’t let her sleep with us so she will get under a pillow that is on top of her bed but sometimes that pillow moves when she does and it ends up a few feet away from her.  This little cozy dog house of a bed is perfect for her.  She can bury herself as far back as she likes and be warm and secure.  She weighs about 18 lbs and fits in it perfectly.
