I would avoid salmon in a raw diet. I believe it is the salmon from the Pacific Northwest that tend to have very high heavy metal levels that can be problematic to a dog eating it on a frequent basis. I also believe there is concern about some sort of notoriously hard to kill (even by freezing) either virus or parasite in raw salmon of the Pacific variety that could pose a threat. If you want to do fish I would stick to things like sardine.
And for wild game meats, venison, elk, rabbit and such are good. Absolutely no bear, and I would not recommend wild hog/pig of any kind as they DO tend to carry trichinosis as well as other various parasites in my experience.
