Q. She is rubbing her rear end on the floor and my neighbor said she needed to be expressed
A. Impacted anal glands are certainly one possibility, as the full glands tend to itch or be sore. Another possibility is tapeworms, which will make their rear end itchy. I recommend getting your pet seen by your vet. They will do an exam to determine the cause of your pet's scooting and express the material from the anal glands (which is very smelly), and clean her up. You can ask them to show you how to express the anal glands yourself at home so you can avoid impaction or infection in the future. If tapeworms are the problem, they will prescribe a broad spectrum deworming agent to remove the parasites. Since tapeworms come from ingesting fleas while grooming, if this is the reason for her scooting, you will need to also treat for fleas to help prevent this from happening again.
