I honestly wouldn’t pay too much attention to the feeding guidelines. I’ve never given my animals as much food as is suggested -usually they get no more than about half the recommendation, and they’re all in great shape- so try to estimate one measurement of food/amount of calories (as the calorie content should be on there) you think suits your dogs.
Then try to calculate price per pound (I believe: price/pounds=price per pound).
If you want to compare the quality, I’d just check on this site for the brand/food.
If the foods you’re looking at seem to be about the same in cost and quality, but have different proteins in them, I’d recommend alternating between them. I try to switch out my dogs’ protein sources, as there are many benefits to it.
