xteacher - you may want to consider yeast overgrowth as the cause of the itching. Dry kibble is formed with binding agents that are carbs/grains which can contribute. Even the wheat, corn, soy free products. Just a thought as your symptoms in our dog turned out to be yeast. Antibiotic treatment was required to get the yeast under control and low carb diet. The probiotic was actually contributing because of the yeast organisms contained in it. We had also taken her off beef, chicken, dairy but it was none of those things. Just a thought.
