Most dogs with food allergies also have environmental allergies. Environmental allergies don't have to occur only from things that are outside. Dust mites, storage mites and indoor molds are high allergens also. Since allergens penetrate dogs skin it is good to bathe your dog very frequently (once per week) with medicated, hypoallergenic shampoo. Environment allergies are impossible to control. A Hepa air filter will help for indoor and outdoor allergens. It may also help to get your dog tested for enviromental allergies so that you can desensitize him to them, or try to eliminate them from the environment. You may also need medications at certain times of the year to help control the allergies. A good choice of medication is Temeril P which is an anti-histamine and steroid combination. There are some herbal formulas that would help also such as: Nettles tincture or the Chinese herbal formula called San Ren Tang, both are available online.
