A puppy lacks social skills. Your adult is going to try and teach him these skills by growling and may even snap or nip at him. This is normal.
Your job is to help the puppy. When big dog starts to say "hey, stop!" then step in and make puppy go do something else. It helps your adult dog feel like her concerns about puppy being rude are valid (they are!!) and helps puppy learn manners.
