I've tried a lot of different dog food brands, with the fosters and all. With Maddie it went
something like this (I don't remember exactly what or when I switched from the Eukanuba. She was very young, and I was just learning about the "truth" of dog foods)
Eukanuba -- Royal Canin -- Natural Balance -- Chicken Soup -- Canidae; did very well on before the ingredients change, then I had to switch again -- TOTW - Nature's Variety -- Innova EVO -- Raw -- Innova EVO/Raw
And
I can tell a different of her skin/coat on all of these foods. She did well on Canidae before the change, but think she does better on the EVO. Dry skin/coat with the NB. I liked it but found myself supplementing with oils and such(too much for my taste) I liked NV, but it made her have really bad dandruff. TOTW made her eyes goopy and gross (same for Mia, which is weird). I loved 100%, but had problems getting a variety, or everything I need for the pirce I needed it LOL so right now the EVO/raw is the best for us
