I would strongly recommend to get her on an anti-anxiety medicine. If she is this aggressive when she normally wasn't before babies, she could also have something else going on. I would have your vet take a look at her to ensure she is otherwise healthy. Your vet will be able to put her on some anti-anxiety medicine to help calm her nerves. She likely being very protective over her babies or she could be in pain somewhere. I am sorry that I do not have a great over the counter or quick remedy. These things take time. You could give her a calming chew or calming collar but I am afraid these wouldn't be strong enough. Plus, I cannot say whether or not they are safe for a nursing mother. Finally, I would try to arrange a place for her to be when you have your company arrive. If you have to board her or take her to someone else's house, you may need to do this. Having a lot of strangers in her house especially if they are wanting to see her puppies will only stress her out more. I would keep her and the puppis separated from the guests unless you are confident that she is better.
