I got the allergy test for my shih-tzu,Gizmo,back and I am kinda shocked. I thought for sure she would have some major food allergies but the only significant value was in pork (which i don't feed anyway). I was not surprised she has problems with some weeds and grasses (yellow dock, marsh elder, Russian thistle,orchard grass, sweet vernal). I know I cant do to much about weeds/grasses other then wiping her down after rolling around. Her highest values were the mites:dust mites and storage mites. I have never heard of storage mites. These guys develop in areas of moisture and high humidity (this is southern Illinois in a nut shell).You find them in house dust and stored food products including PET FOOD. I need recommendations on how to deal with these mites. I was looking into air purifiers. Any opinions? I know I can only do so much but I want to do all I can for her.
