It could be just normal puppy breath. Some people feel like it doesn't smell good. If she tends to eat poop, this could also be the cause. With her being so young, I would not expect her to have any dental tartar causing a smell. If it continues or it gets worse, I would have your vet take a look at the mouth to ensure there isn't an infection somewhere.
