I have a small dog, well three small dogs, but one strange one. Ever since he has been a puppy he likes to wedge himself behind my neck and back and the couch cushion. I would think it would get very hot back there; it certainly is on my neck/back. Take a nap in a chair or on the couch and wake up to find him wedged there. Read a book or computer, he slithers in for the spot. So what strange behaviors do your pets perform?
