Food manufacturers have already proven time and time again they don't care much for humans (surely there are complex cost/profit margin with law suits algorithms being run) so for dogs I figure it's a hundred times worse if not more. Much better to make your own dog food if you don't mind doing it every few days. There's a million recipes online that can be made for far less money than most of the stuff that pretends to be healthy at the store. https://www.aforkstale.com/easy-home...kpot-dog-food/
As for the companies out there, of all the research I did years ago (and I shudder to remember), one of the few companies that I trust are these folks. https://www.grandmalucys.com/ Their food comes freeze dried, just scoop out what you think you need, add warm water and walla, instant dog food. I try to keep a 10 lb bag on the shelf at all times as it would be a perfect MRE style food if the poop should ever really hit the fan.
