One of my female pointer dogs racked up numerous vet bills where they did skin scrapings, I tried benadryl, vet put her on repeated courses of antibiotics and prednisone and none of these resolved her ongoing skin
issues. So I began trying different more expensive dog
foods that were limited ingredient diets. When I tried her on California Naturals Lamb and Rice; it finally put a stop to her skin issues. It turned out that she was sensitive to any dog food that contained chicken.
