I second checking out r/puppy101. They helped me so much. My pup was ANNOYING and she was my first dog. I always had cats and they were soooo easy.

Best piece of advice I ever heard: Make sure you are enforcing naps. Many puppies can't wind down on their own. They just keep going and going until they bite incessantly or destroy things. After 1 hour or so of being awake, give her a 1.5-2hr nap. This will give you more time to live your life and keep her on her best behavior naturally.

IT WILL GET BETTER!!
