This is funny as hubby and I were just discussing this very thing a couple days ago.
I had a friend who even last year was always telling me about her dog and how she liked to sleep under the covers. I was like, Dude! That's not safe! She'll suffocate! You'll kick her! How do you KNOW she wants under the covers? That's just so stupid!
ROFL Well by golly... I got my little yorkie... she burrows under the covers, and if you take her OUT, she goes right back under. She sleeps either by or on my tummy (however it happens to be).... so I have a little more sympathy for my friend now. Some dogs just really do like to sleep under the covers. And it won't kill them... at least it hasn't yet
