I had a terrible time with Blue Buffalo with my dogs- ear infections, itching and diarrhea.
I like Fromm grain frees a whole bunch (only complaint is the stool is a bit large) and PetGuard Lifespan (basically a chicken/rice). They work well for my 4 dogs.
There is also California Natural that has some very simple grain free formulas you might try your dog on. Some are just so very sensitive to all the grains and herbs and “kitchen sink” formulations and it sends their body into itch overdrive.
If you don’t mink cooking, you could look into DogDishDiet.com as well. Crock pot food.
Hope this helps and your guy feels better soon!
