I have a friend with a german shepherd. At a sleepover, I went to sleep in the living room (at 5:00am) and woke up with his shepherd asleep with me. Also, his (my gosh freaking scary monster) rottweiler stuck its nose in my ear. I just wanted to get up so bad but the dog was so dang sketchy and freaked me out. About the size of a black bear and like 200+ pounds (not fat, pure bone and muscle too)
