She is probably just itchy from the sanitary shaving at the groomers. Maybe they used too close a blade and irritated her a little. Either way she should be fine. BTW I got a kick about of your "NinaPants" name. My female is named Brandy and we usually call her BrandyPants. I have no idea where the pants part came from but we all use it. Sometimes we just call her Pants or Miss Pants. I have a little male named Titan also and lately we have started calling him TiteyPants.....
