The rescue I work with had a large amount of Earthborn donated. All of the dogs but mine did great on it (but he's allergic to EVERYTHING). I used to feed mine Canyon Creek (higher end Purina) ~ it was the only thing that didn't make him itch like crazy. Then it was discontinued, of course. Now he's on Purina Beyond Adventure (also made by Purina and still expensive). He was doing fine on it since we discovered it last spring or summer but now he's starting to react a bit to it. Not quite as bad as he does to everything else but we've tried just about every food out there . . . Various types of grain free, organic, Science Diet, etc. He seems to have a problem with chicken in almost anything. We've tried Venison, Lamb, Salmon, etc. I have a large flock of Muscovies and always have too many males. Our next step is going to be to try making our own food if he can tolerate duck . . .
