Spending time there will be important for her to build self-confidence and cope with being on her own. Allowing her free run of your home gives her too many unsupervised choices as to what to chew, jump up on, chase, etc. Use of a confinement area also reinforces her denning instinct, which helps with housetraining later. For a place to call her own, a crate or small gated area works well. Provide her with chewable items in this area to teach her what is hers.
Confinement balanced with free time helps to teach a puppy self-control.
A puppy that shadows your every movement may tend to overbond and become very stressed when left alone. If left alone excessively she will not receive the social contact she needs, which often leads to boredom-related behaviors like shredding newspapers. Balance the time she spends in her den with supervised freetime. As her house manners improve, her greatest reward can be to receive more freedom. If a puppy complains loudly about confinement, do not release her immediately or she will get louder the next time.
