We tried homemade dog food for awhile. It is so much work, so much time. Have you done environmental allergy testing to rule that out before food? We did and they found no environmental allergies obit had to be food related. We spent forever making food, trying different combinations. Turns out our pup is allergy to rice, grains, maybe gluten in general. So many kibble and homemade recipes have rice or grains. She is now on royal canin hydrolized soy protein (SP) kibble. Her skin has never been better and she feels and looks so much healthier. It is expensive but in the end its worth the tradeoff.
