Are you trying to eliminate flax because of its phytoestrogen properties?
One of my dogs cannot have flax (among lots of other things), but he’s fine with peas. So, these foods are flax free, but you’ll need to check for peas in them: Addiction Viva La Venison, Canidae Pure Sky (Diamond, I know yuk!), The Honest Kitchen Thrive, First Mate Chicken and Blueberries, Acana Duck and Bartlett Pear (original formula, not “Singles.”).
Flax is frustrating, I know. It’s everywhere, isn’t it! My dog gets terrible loose stool when he eats flax. Do try the Dogfoodwizard.com like C4C mentioned. I asked the site creator to add flax and last I looked, it’s an option on the search tool.
