The only way you are going to be able to tell what she is allergic to is either by allergy tests or an elimination diet. AND the only way you are truly going to know the ingredients is with a homemade diet. It could be anything in the dog food that is causing the allergies. However, if you can't make a homemade diet, then one food company that I do trust is Wellness. They have a line of dog food, called Simple Solutions that has 3 different flavours:

It would take about 6 weeks for allergies to disappear.
