It is possible that this will give her much relief.  However, without knowing your current situation as to whether the area is free from fleas or mites, this might be an ongoing problem.  Also, I have a 10 year old 9 pound shih tzu who is allergic to almost everything and we have to give her pills from the vet.  But before we found out about her immense allergies, I did use the nu-stock on her red and raw scratch areas and it definitely got rid of them.  The unfortunate part was they kept coming back due to her allergies.  Hope this helps.
