Oh, be warned! My Dad used to play that same "Bed Monster" game with our Great Dane. Much too late, he realized that she then assumed any lump in the blankets was going to "get" her - even if they were lumps she created by napping on a smoothly made bed. She would then make pre-emptive strikes on those nasty lumps - and chew holes in the blanket! My Dad realized he had created the world's biggest (95-pound) moth, and my parents quickly got rid of their electric blanket, so poor Gracie wouldn't electrocute herself! Blankets were never safe again!
