Talked to my vet and they don't think it is the food. If it was a sensitivity to food, then their skin would have sores//bumps and redness in the arm pit area. They recommend a special skin shampoo called Pyoben. It is for skin conditions like scaling, flaking and itching. Going to try this for a month and see if it gives Teeka and Tatiana some relief! Thanks everyone for the awesome advice. This is why I love YT!
