My puppy likes pressure and warmth?

Hi there! As far as I can tell (from having puppies multiple times) this is completley normal! We had one puppy that would try to get between your back and the couch when you were sitting and tried to get in people's shirts. It just reminds then of when they were young and got to cuddle up to "mother" and the other "kids". A lot of puppies do this and it should go away with time just like ours did! (: As far as suffocating her or pushing her off the bed goes, don't worry about it. If the oxygen to her brain begins to slow she will try to get away and will almost ALWAYS get away in time. (: Pushing her off could hurt her, but she'd be woken up if she would start to be pushed. Hope this helps! ^.^
