I started about 5 months ago with Zoey on Evo. I will never ever use any other dog food for her. She has sevure allergies and normally has really dry flakey skin. Her coat is amazing now, and she has so much more energy. I just recently switched Sage over to that food and he is doing well too. Evo is my favorite dog food and I will always have it in my house. Chicken Soup is what I feed T.j, and he does fine on it.
