I'm late to the party, and only skimmed the previous comments… but I just wanted to add that we're huge Honest Kitchen fans here. It's a great, in-between step for us between a fully raw diet and kibble. My dogs got hooked on the Zeal (fish) recipe, which we happened to order on a fantastic buy-one-get-one-free deal for the 10 pound boxes (and they loved every pound of it!). Others in our regular mix now include Embark (grain-free turkey), Force (grain-free chicken), Keen (turkey and oats), and Preference (meat-free veggie mix that allows you to add any protein you'd like, in whatever ratios you feel is appropriate).
If high protein is a concern, you might want to try Acana, also by Champion Pet Foods, the makers of Orijen. We don't really feed Orijen anymore since they bumped the protein ratio up, but my two do very well on Acana. I do a lot of fish-based kibbles. Acana Pacifica is less expensive than Orijen Six Fish, for example... and definitely less than Ziwipeak. May be something to consider...
Edited to add: the Honest Kitchen also has a line of natural digestive supplements called Perfect Form that's pretty easy to add to any of their dehydrated meals, and helps smooth things out on the other end.

They offer cheap sample pouches on the site if you don't want to spring for a whole canister (they also offer sample versions of everything else). I keep a canister on hand for the occasional stomach upset, and it works pretty well for us in the months when canned pumpkin is not available…
