Newborn puppies keep opening their mouths and panting

There are three situations when newborn puppies keep opening their mouths and panting: there is amniotic fluid in the nose, the coating blocks the nose, and the amniotic fluid chokes the respiratory tract. In the first two cases, you can wipe the dog's nose with clean gauze to allow the dog to breathe normally. If the dog is choked by amniotic fluid, you can turn the dog upside down and pat the back gently to drain the amniotic fluid. Note that puppies' bones are very fragile and should be handled gently.
