This is funny! This is the first time Belle has ever slept on the back of her couch. I keep a small loveseat around for her to sleep on (the only furniture she is allowed on). I came home the other day and she was sleeping on top of the back of the couch. Her cousin Sassy was here for a visit not to long ago, and I think she learned it from her!
Ever seen a dog sleep on the back of a couch?
