Puppies, usually are very friendly and demure. If your puppy seems to be adamant or dominating, it could just be that she has a lot of energy which needs to be drained. Make her play and get sufficient physical exercise. While it is important to tire a puppy, they should be made to engage in mentally exhausting exercises vs physical as their bones are still developing. Giving your puppy mental exercises and play time will definitely calm her down.
You can work on teaching her a lot of tricks in the house, like fun clicker tricks which are mentally stimulating and keeps the dog's brain active. Most dogs enjoy clicker training because it's not obedience training, nor is discipline oriented, and a good dog training should always be a mix of both motivation and discipline.
