The list is not comprehensive and every food available is not listed, that's why there is a way to do your own scoring. There are lots of high quality foods not on the list. Fromm is an outstanding food (one of the best, in my opinion).
Feed a variety of proteins. Fish is especially important because of the good omegas. Some of the grain-free foods are a bit too high in protein. Think about what a dog in the wild would do . . . they take down the prey and first eat it's organs. That includes stomach and intestines. Most prey is vegetarian and so dogs get their veggies and greens from that source. The last to be eaten is the least desireable flesh/muscles.
You are right to be concerned about giving your dogs too much protein. I've read that dogs eating too much protein have difficulty recuperating from injuries, etc. As people become more informed about the dangers of grocery-store dog food, including bad grains such as white rice or corn, some dog food companies have capitalized on that by advertising "grain-free high-protein" which may not be best for all dogs. Be sure your dogs' food has some good carbs like sweet potatoes or oats, and some greens.
Good job feeding healthy treats! So often, my clients would buy our healthy foods but give Milk Bone or Pup-eroni or some other horrible treat and wonder why their dogs were still having health problems. Once healthy treats were given, the dogs just thrived.
