Can you all give advice on dog food that you recommend that is made in the US and also sourced here? I initially fed my dog Pedigree, but read corn is not a good ingredient (first ingredient listed with Pedigree), I tried a grain free and my dog had diarrhea and was very sensitive to it. I then tried Purina (I think from a recommendation?) but it seems it may not be completely sourced in the US(looks like a lot of dog food isn't) and researched it online to not the best reviews. Any recommendations are appreciated! Thanks!
