My dog has allergies as well. Unfortunately, when you try to find a single protein/carb diet, the highest rated foods will add something stupid like eggs or chicken fat, which are red flags to an allergy dog. Or they mix several proteins, which makes the feed no longer useable. I can’t feed my dog fish oils and have to give him omega 3’s via Flax Oil. My dog can’t tolerate raw. I may have to go to cooking to get around the issues with bagged food.
According to my dog’s dermatologist, the proteins to avoid are poultry (chicken and turkey) and lamb, since they have been overused in dog food. Duck, Rabbit, Kangaroo and Bison are considered “exotic” since they are not included in mainstream dog food. I’ve seen some brands offer water buffalo (Southeast Asia, India and China). Some of these manufacturers have got to learn that less is more. I will not feed Hills or Iams special diets from the vets. I keep hoping I can search this site to find a food that will meet my needs. Good luck to us all.
