I have had the exact same problem with my pure bred lab. She is 3 and I have spent thousands at the vet on her. Chronic ear infections, yeast infections, stomach boils, and itchy as can be. I have finally came to realize after environmental allergy tests she is allergic to dust mites as well as storage mites. These both found in dry dog food. She also is allergic to ALL meat protein. This has been so difficult and no vet has helped me. I finally read online about the meat allergy and thank goodness I did. I have since switched her to natural balance wet vegetarian dog food. And it has made ALL the difference. Her ears are crystal clean, her belly is happy and her skin is happy. This has never happened for me before, to tell you how bad it was I had an appointment with a dog dermatologist booked before this food. We tried zignature, elimination diet, royal canin, ultamino, hydrologized food, limited ingredient and nothing worked but this wet vegetarian food is amazing. She loves it too! I would recommend it and I also give probiotics with her dinner to her. She literally runs to her bowl now as does my other dog without allergies. I really hope this helps, I truly know how frustrating dogs with allergies are! If you have any questions please let me know!!:)
