Diamond. Although, our older Springer prefers kraft mac and cheese, or mashed taters. When I was a kid, we never bought dog food. They ate what we ate.
Taste of the Wild, mostly the one that has fish. Our pit bull has a sensitive stomach, and allergies. He likes this food, and does well on it. Lately we've been able to buy it at Rural King.
Royal Canin Boxer. We tried a few different types of Premium Edge, but our female has a sensitive stomach, so we did some research. Ended up that breed specific food is tailored around some issues that are known in those breeds. Also it has enough fish oils and joint vitamins that we don't add them to the food anymore. It's kinda pricey, $2 a pound, but the dogs are our family and worth every penny.
Exceed lamb and rice. Harder to find a higher protein or fat food. I have always fed my working dogs Exceed. Same stuff IMPD was feeding their dogs last I knew.
