Okay so I had sinusitis about 3 weeks ago.. And I've got it again. The doctor thinks something is triggering it and there is a large chance that I'm allergic to dog dander. Unfortunately, I absolutely love dogs, and I don't want to get rid of mine. I know there isn't anyway to get rid of allergies but I just need to get my tolerance to the point where I'm not getting sick every 3 weeks. To strengthen my immune system I'm drinking lots of DanActive and taking VSL 3 but I need help on how to reduce dog dander. Advice?
