Previously I fed my dog with Eukanuba but then I switched to Acana Salmon & Potato because I was told some dogs might be allergic to chicken or beef and my dog was scratching a fair amount. Acana Salmon & Potato was doing fine for my dog but decided to switch to Orijen to try out. But haven't started feeding my dog with Orijen yet. The pack I bought is the normal Orijen for adults. If my dog is allergic to it then I'll change to Orijen fish.

I don't think Science Plan is as good as those brands mentioned in the topic thus far. I do think Science Plan is better than Eukanuba but Acana and Orijen are definitely better. Not too sure about Blackwood but I see many people voted for Blackwood.
