My new little baby has stinky puppy breath

SHe has had a vet exam, had her first set of vaccines, and been dewormed. She is behaving very normal, and she's active.
Why does she have this smell? I thought it was because ofthe diet she was on, but since bringing her home , Miley has chosen to eat Suzi's kibble which is higher quality.
Do i need to worry about her sting breath? Suzi never had this. How do I get rid of it? Is this normal in younf puppies? At first i thought something was wrong with her!
