Vet ruled out mites and said she has some kind of inhalant allergy (because our houses are so tight shut during winter, apparently dust motes and molds are a problem) plus he found evidence of yeast dermatitis and gave me sebozole shampoo to use on her twice a week. Well it's been 2 weeks (he said we should see improvement by now) and not only is she still scratching, but her fur is all but gone on her belly, she's back to chewing her feet and the skin on her belly is almost like an old lady's wrinkly dry skin. She's getting new areas of the brown spotted 'rash' on the inside of her rear leg. (This is the 'yeast') Vet says it's not a food allergy. We got an air purifier to help with any allergens. I've had a call in to my vet but he hasn't returned it. Has anyone else ever dealt with this problem? We've got snow and deep cold coming and her little sweaters aren't going to help on her belly where there's no hair.

Help, please?
