It’s true that much is lost in the heat process. There are brands that use less /lower heat in the processing of foods. And most add nutrients after to replace what is lost like probiotics.
Always always always check the date on the food before buying. They are usually dated 1 yr later.
There’s certainly much better & much worse options. Choose a few of the best brands that are within your budget and your dog does well on and rotate every few months. No one food should be fed for the entirety of a dog’s life anyway.
There is no one perfect food/diet that is best for all dogs. Every dog is different. Every family has different means and budgets.
Stay away from the really cheap stuff, do your homework and pay attention to how your dog does on a particular food.
We all just do the best we can.
