YES, Blaze sleeps on his back a lot, and it looks really goofy! Sometimes he'll lay down by a wall or the side of the house and sleep with his legs up against the house or wall! It's really funny! He will sleep anywhere on his back, but did moreso as a puppy. This is only half the time he does sleep, but I like to take pictures of him before he wakes up (when he does his awkward positions!)...I'll try to post a couple here sometime.
