I also top with canned, instead of feeding it as the bulk of their food. Honestly, I rotate around a lot with canned (dry as well, but less so) whenever I’m at PetSmart, PetCo, or Four Paws (my usual specialty store i stop at) I get whatever high quality is on sale.
I also keep a bag of Sojos (i rotate flavors, haven’t tried the new lamb yet, as it’s hot out and one of mine gets real warm on lamb) for when I don’t have any canned on hand. As long as it’s all good quality, your dog shouldn’t have much problem switching canned flavors often. If something is giving him the runs, take a look at what’s in it, and it could be an intolerance to one of those ingredients
