OK my fellow food experts.....Has anyone had their dogs on Natures Logic and Fromm Grain Free Surf & Turf? I have my boy on NL Duck & Salmon right now and hes doing good, but I'm wondering if Fromm is even better? Opinions???? I've been comparing the ingredients and Fromm has some good stuff like Glucosamine and Chondroiten that NL does not have.........hmmmmmm decisions decisions!
