Try Canine Caviar, Addiction and FirstMate. Those are three brands that I feed my dog with food intolerance issues, one of which is fish.

You could also give this a shot: dogfoodwizard.com. It’s not foolproof, so you’ll need to double check the ingredients for foods it finds that meet your criteria. There are also foods that aren’t listed.

What I do on a regular basis is go to Chewy.com and go through the ingredients of hundreds of foods, one at a time. It’s the only way to be sure.
