I use TOTW Pacific Stream, the one with salmon. It works very well for my dogs and was the only food I found that my super allergic Zelda (RIP) could eat and not get lots of allergy issues.I don't know about the salmon oil thing though. Some here say the processing the food negates the salmon oil benefits, I don't know. In any case, I'd change the food and see how Dozier does with that change, it will take a couple of months to be sure it's done what you'd hoped, before adding any other changes to his diet. If you don't do the changes one at a time you won't know which had the desired effect or caused the new problem.
