I delt with it daily..One of my Schnauzers has terrible allergies..He has scratched until he bled. I had him allergy tested and they found he is allergic to all grains which is in most ordinary dog foods..He now eats sweet potato and chicken. After about 6 weeks all the itching has stopped. He is a much happier dog and so am I happy...If you don;t want to allergy test which is expensive......(500 dollars or more) try giving brown rice and meat. I supplement his diet with a multivitamin. It will take at least one to three months after changing diet to get results but it is worth the effort for you and the dog.
