I would start by trying a limited ingredient diet, I’m fond of Acana singles pork and apple. I also like Orijen Six Fish as a place to start for digs with allergies. Allergy testing is expensive, I’ve found that an elimination diet was a less expensive and more accurate way to determine what my dog could eat.
Check out DogFoodWizard.com for my food selector tool, you can tell it to exclude foods that contain poultry and any other suspected allergens for your girl and it should give you a whole list of foods she can eat.
