I agree with all the above and would also like to mention that she may need her anal glands expressed as well. Leeo has that particular issue and he either scoots, licks or bites at his rear. If it is anal glands and left untreated it can lead to other health issues as well as skin infections. It could be a little bit of everything. Hope she feels better! I also changed to TOTW grain - free dog food with much better results with Blu Boy and his allergies.
