Flea Allergy?

We have been fighting for years now with what we think is a flea allergy in our Shihtzu, but now are wondering if it might be a food allergy.

We feed Nutro Venison mix. It lists lots of natural ingredients, but maybe there is something in it that is bothering her. She has champagne colored hair and so I just figured since she is light colored she is prone to itchy skin, and allergies.

What food if any would you recommend. I can get Wellness here at Petsmart. Thanks for any help.
